this change adds code to CreateGetOrderLimits to filter
out any nodes that are not in the placement specified
by the segment. notably, it does not change the audit
or repair order limits. the list segments code had to be
changed to include getting the placement field from the
database.

We avoid putting more than one piece of a segment on the same /24
network (or /64 for ipv6). However, it is possible for multiple pieces
of the same segment to move to the same network over time. Nodes can
change addresses, or segments could be uploaded with dev settings, etc.
We will call such pieces "clumped", as they are clumped into the same
net, and are much more likely to be lost or preserved together.
This change teaches the repair checker to recognize segments which have
clumped pieces, and put them in the repair queue. It also teaches the
repair worker to repair such segments (treating clumped pieces as
"retrievable but unhealthy"; i.e., they will be replaced on new nodes if
possible).

This code is essentially replacement for eestream.CalcPieceSize. To call
eestream.CalcPieceSize we need eestream.RedundancyStrategy which is not
trivial to get as it requires infectious.FEC. For example infectious.FEC
creation is visible on GE loop observer CPU profile because we were
doing this for each segment in DB.
New method was added to storj.Redundancy and here we are just wiring it
with metabase Segment.

This modification introduce support of the new "desired node" field of download segment/object.
This can be used to request more nodes than the suggested minimum. It can be used to achieve better performance in exchange of using more bandwidth. (more parallel downloads).

Most of our (~integration) tests based on testplanet runner.
However running testplanet for each test make the testing process slow.
It seems to be better to use real unit tests (without db dependency) when it's possible.
This patch makes small modification to make it possible to test orders.Service with real unit test.
As the existing unit test of `service.go` is isolated with `_test` package name, it's moved to an `_integration_test.go` file to make place for the unit test.

Orders from storage nodes are received by SettlementWithWindowFinal method. There is a stream which receives all orders and after getting
all orders we are inserting into DB storagenode and bucket bandwidth. Problem is with bucket bandwidth which is stored through cache which is often using context from SettlementWithWindowFinal stream to perform DB inserts and its doing this in separate goroutine. Because of that is possible that SettlementWithWindowFinal is finished before flushing was finished and context is canceled while doing insert into DB

we have two more fields in the database (noise_proto and
noise_public_key) that now need to go into pb.NodeAddress when
returning AddressedOrderLimits.
the only real complication is making sure type conversions between

For bucket_bandwidth_rollups we are trying to insert lots of entries
with empty bucket name and project id. Those are inserts from orders
created by repair, audit and GE. High load on the same primary key
(the same range) is causing many retries and that's affect all inserts
as we are putting 1000 entries into DB a once.
This change solves this problem by not storing into
bucket_bandwidth_rollups other actions then GET and PUT. Those actions
are only important from bucket bandwidth usage perspective because
those are actions performed by users. Other actions (repair, audit or
GE) are also stored in storagenode_bandwdith_rollups so we will still
have access to them e.g. for statistic purposes.

Sorting by primary key before inserting data into DB is fixed.
Earlier we were sorting input slice of BucketBandwidthRollup but then
we were putting all entries into map to rollup input data. Iteration
over map with a range loop doesn't guarantee any specific order so we
were loosing sorted order when we were creating with this map slices to
use with DB insert.
New code is also using map but when map is full its sorting map keys
separately and iterates over them to get data from map.

bucket_bandwidth_rollups table
We have performance problems with updating bucket_bandwidth_rollups. To
improve situation we can stop storing allocated bandwidth in this table.
This should reduce large number of updates which are comming from
metainfo endpoints, repair workers and audit.
Next step will be to drop `allocated` column completely from
bucket_bandwidth_rollups.
Allocated GET bandwidth is all we need and we are keeping it in
bucket_bandwidth_rollups table.

Currently the primary key of the underlying rollup table has the
primary key being the bucket name, but we used to sort by projectID.
This caused dead locks due to the contention during updates/inserts.
We should reevalute if bucket name being the primary key is the right
way for this table, this should stop the long running and failing attempts tho.

ReverifyPiece() works by downloading one piece in its entirety, rather

For nodes in excluded areas, we don't necessarily want to remove them

excluded areas.

inconsistency
The original design had a flaw which can potentially cause discrepancy
for nodes reputation status between reputations table and nodes table.
In the event of a failure(network issue, db failure, satellite failure, etc.)
happens between update to reputations table and update to nodes table, data
can be out of sync.
This PR tries to fix above issue by passing through node's reputation from
the beginning of an audit/repair(this data is from nodes table) to the next
update in reputation service. If the updated reputation status from the service
is different from the existing node status, the service will try to update nodes
table. In the case of a failure, the service will be able to try update nodes
table again since it can see the discrepancy of the data. This will allow
both tables to be in-sync eventually.

Batching of the order submissions can lead to combining the allocated
traffic totals for two completely different time windows, resulting
in incorrect customer accounting. This change will group the batched
order submissions by projectID as well as time window, leading to
distinct updates of a buckets bandwidth rollup based on the hour
window in which the order was created.

In the situation where the flushes take longer than the incoming
rate of writes, the RollupsWriteCache will take every connection
in the database pool and use them forever. Instead of doing that
and taking down satellite availability, bound the number of flush
operations that it will perform and drop incoming writes earlier
to keep memory usage constant.
Adds monitoring events for if any flushes or updates are lost.

Satellites set their configuration values to default values using
cfgstruct, however, it turns out our tests don't test these values
at all! Instead, they have a completely separate definition system
that is easy to forget about.
As is to be expected, these values have drifted, and it appears
in a few cases test planet is testing unreasonable values that we
won't see in production, or perhaps worse, features enabled in
production were missed and weren't enabled in testplanet.
This change makes it so all values are configured the same,
systematic way, so it's easy to see when test values are different
than dev values or release values, and it's less hard to forget
to enable features in testplanet.
In terms of reviewing, this change should be actually fairly
easy to review, considering private/testplanet/satellite.go keeps
the current config system and the new one and confirms that they
result in identical configurations, so you can be certain that
nothing was missed and the config is all correct.
You can also check the config lock to see what actual config
values changed.

Previously the object range was not used for calculating order limit.
This meant that even if you were downloading only a small range it would
account bandwidth based on the full segment.
This doesn't fully address the accounting since the lazy segment
downloads do not send their requested range nor requested limit.

errs.Class should not contain "error" in the name, since that causes a
lot of stutter in the error logs. As an example a log line could end up
looking like:
ERROR node stats service error: satellitedbs error: node stats database error: no rows
Whereas something like:
ERROR nodestats service: satellitedbs: nodestatsdb: no rows
Would contain all the necessary information without the stutter.
