With this change we are removing code responsible for deleting objects
and supporting server side copies created with references. In practice
we are restoring delete queries that we had before server side copy
implementation (with small exception, see bellow).
From deletion queries we are also removing parts with segment metadata
as result because we are not longer sending explicit delete requests to
storage nodes.

Change is adjusting CommitObject to use `pending_objects` table to
commit object.
Satellite stream id is used to determine if we need to use
`pending_objects` or `objects` table during commit.
General goal is to support both tables until `objects` table will be

first change to move pending objects from objects table.

To be able to decide if we need to use `pending_objects` table or

This change adds only schema definition of pending_objects table and
small amount of supporting code which will be useful for testing later.
With this table we would like to achieve two major things:
* simplify `objects` table, before we will start working on object
versioning
* gain performance by removing need to filter `objects` results with `status` column, which is not indexed and we would like to avoid that

Segments loop implementation is using lots of memory to convert
alias pieces to pieces for each segment while iteration. To improve
situation this change is reusing Pieces between batch pages. This
should signifcantly reduce memory usage for ranged loop executions.

Currently, we have issue were while counting unhealthy pieces we are
counting twice piece which is in excluded country and is outside segment

placement.AllowedCountry is the old way to specify placement, with the new approach we can use a more generic (dynamic method), which can check full node information instead of just the country code.
The 90% of this patch is just search and replace:
* we need to use NodeFilters instead of placement.AllowedCountry
* which means, we need an initialized PlacementRules available everywhere
* which means we need to configure the placement rules
The remaining 10% is the placement.go, where we introduced a new type of configuration (lightweight expression language) to define any kind of placement without code change.

..instead of using segment_copies and ancestor_stream_id, etc.
This bypasses reference counting entirely, depending on our mark+sweep+
bloomfilter garbage collection strategy to get rid of pieces once they
are no longer part of a segment.
This is only safe to do after we have stopped passing delete requests on
to storage nodes.

Currently we are using Reliable to get missing pieces for repair
checker. The issue is that now checker is looking at more things than
just missing pieces (clumped/off, placement pieces) and using only node
ID is not enough. We have issue where we are skipping offline nodes from
clumped and off placement pieces check.
Reliable was refactored to get data (e.g. country, lastNet) about all
reliable nodes. List is split into online and offline. This data will be
cached for quick use by repair checker. It will be also possible to
check nodes metadata like country code or lastNet.
We are also slowly moving `RepairExcludedCountryCodes` config from
overlay to repair which makes more sens for it.
This this first part of changes.

This combines the ListStreamPositions and GetSegmentByPosition
calls with a ListSegments call that now knows how to return
only the segments within a Range, just like ListStreamPositions.
It would theoretically be possible to also include the
GetObjectLastCommitted call by having it do one of three
queries based on the incoming request range, but that would
mean duplicating the data for the object in every single
row that is returned for each segment in the range.
One gross thing that ListSegments has to do now is update the
first segment returned with the information from any ancestor
segment because GetSegmentByPosition used to do that. It only
updates the first segment so that it doesn't do O(N) database
queries. It seems difficult to have it do a single query to
update all of the segments at once. I'm not certain this change
should be merged on this basis alone.
This change has made me think a couple of things should happen:
1. Server side copy with ancestor segments strikes again
making the code less clear and potentially more buggy
or inefficient for a rare case (empirically <0.1%)
2. The download code requests individual segments from
the satellite lazily as part of its download which
requires the satellite telling it the locations of
all of the segments which requires the satellite
querying the locations of all of the segments. Instead
the download RPC could return the orders for all of
the segments for a range and the download code could
issue N download calls rather than 1 download call and
N get segment calls. I believe both sides of the code
paths would be simpler and more efficient this way.
3. In looking at the timing information for downloads when
testing this, we really need to focus on getting the
auth key and bandwidth limit verification times down.
Here's the timing I saw:
- 42ms: validate auth
- 52ms: bandwidth usage checking
- 14ms: get object info
- 26ms: get segment position info
- 26ms: getting the first segment full info
- 20ms: unaccounted for by spans
- 6ms: creating the orders
This change will remove 26ms, but there's a good 90ms
in just validation. With improved semantics hitting the
database only once and improved validation, a download
rpc taking ~30ms seems doable compared to our current
~200ms.

We want to eliminate usages of LoopSegmentEntry.Pieces, because it is
costing a lot of cpu time to look up node IDs with every piece of every
segment we read.
In this change, we are eliminating use of LoopSegmentEntry.Pieces in the
node tally observer (both the ranged loop and segments loop variants).
It is not necessary to have a fully resolved nodeID until it is time to
store totals in the database. We can use NodeAliases as the map key
instead, and resolve NodeIDs just before storing totals.

Currently, to get number of entries in segments table we are doing
heavy SELECT count(*) operation. For biggest satellite it's taking
25min now. We are using this method to get stat before and after
segments loop so it adds almost 1h to overall loop time.
With current version of crdb we are using this additional code won't be
used because global configuration for stats refresh rate is inaccurate
for such large table like `segments`. Soon we should be able to upgrade
crdb and be able to adjust refresh rate per table and configure it to
satisfy defined threshold.

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 is first attempt to use AliasPieces inastead Pieces with
segments/range loop. So far we were always using Pieces
which are always converted from AliasPieces for easy use.
Side effect is that using NodeID with loop observers is heavy
e.g. we are using maps which behaves slower with NodeIDs.
We are starting with audit observer because it's easy to change
it as in feact it doesn't need access to real NodeID at all. We just
need to reference node in some way and this way is NodeAlias.

We have an issue where object can appear in two different listing pages.
It's because protobuf listing cursor doesn't have version included and
now we can have internally versions higher than 1. On satellite side
version 1 was always used as a default cursor version.
As a workaround for existing implementation of libuplink library we will
use always maximum version for listing cursor on satellite side.
Fixing protobuf and libuplink implementation will happen later.
