Estimate speed of the uploads by calculating the time a client has been in a non-congested state. Storage node is uncongested when it has used up over 80% of its maximum concurrent requests capacity.
Currently it's disabled by default.
Add the upload size to the log lines of the storagenode Upload endpoint
to provides the information to Storage node operators.

When we call ordersStore.BeginEnqueue, the unsent orders file for that
satellite and hour is prevented from being sent. It is freed when the
commit callback returned by BeginEnqueue is used. This change ensures
that we always call the commit callback, even when we have an empty
order or an order with Amount <= 0.

This change accomplishes multiple things:
1. Instead of having a max in flight time, which means
we effectively have a minimum bandwidth for uploads
and downloads, we keep track of what windows have
active requests happening in them.
2. We don't double check when we save the order to see if it
is too old: by then, it's too late. A malicious uplink
could just submit orders outside of the grace window and
receive all the data, but the node would just not commit
it, so the uplink gets free traffic. Because the endpoints
also check for the order being too old, this would be a
very tight race that depends on knowledge of the node system
clock, but best to not have the race exist. Instead, we piggy
back off of the in flight tracking and do the check when
we start to handle the order, and commit at the end.
3. Change the functions that send orders and list unsent
orders to accept a time at which that operation is
happening. This way, in tests, we can pretend we're
listing or sending far into the future after the windows
are available to send, rather than exposing test functions
to modify internal state about the grace period to get
the desired effect. This brings tests closer to actual
usage in production.
4. Change the calculation for if an order is allowed to be
enqueued due to the grace period to just look at the
order creation time, rather than some computation involving
the window it will be in. In this way, you can easily
answer the question of "will this order be accepted?" by
asking "is it older than X?" where X is the grace period.
5. Increases the frequency we check to send up orders to once
every 5 minutes instead of once every hour because we already
have hour-long buffering due to the windows. This decreases
the maximum latency that an order will be reported back to
the satellite by 55 minutes.

On run, write the storage directory verification file.
Every time the node runs it will write the file even if it already exists.
The reason we do this is because if the verification file is missing, the SN
doesn't know whether it is an incorrect directory, or it simply hasn't written
the file yet, and we want to keep nodes running without needing operator intervention.
Once this change has been a part of the minimum version for several releases,
we will move the file creation from the run command to the setup
command. Run will only verify its existence.

* Add all new orders to the orders filestore instead of the database.
* Submit orders from the filestore to the new satellite SettleWindow
endpoint.
The orders filestore will eventually replace the orders DB completely.
For now, we will still be checking the orders DB and submitting those
orders if they exist. In a later release, we will completely remove the
orders DB, but we need both the DB and filestore for the transitionary
period.

We only sync free disk and available space, if necessary, on startup. If the
SNs disk fills up with non-storj data, we will not know about it when reporting
available space to the satellite.
Solution: whenever we check the node's capacity, double check free disk.
If free disk < than expected available space, return free disk.

When an uplink or repair work finishes uploading a piece to a
storagenode, it has no reason to wait another round trip after the piece
is committed to gracefully close the connection - in many (most?) cases,
the connection is simply canceled once the upload is complete. This has
the unintended side effect of producing a lot of "piece canceled" logs
and metrics on the storagenode side, when the reality is that the piece
uploads were successful, and not really canceled. This commit fixes
that.

Part 2 of moving usedserials in memory
* Drop usedserials table in storagenodedb

verification
* Update order limit grace period to be only one hour - this means
uplinks must send their order limits to storagenodes within an hour of
receiving them

When we receive a piece deletion request, include the number of piece
IDs we couldn't add to the queue in the reponse
Change-Id: Ibebbe92ac50105bb5c74b18211ed38d468eb33f3
To improve delete performance, we want to process deletes asynchronously
once the message has been received from the satellite. This change makes
it so that storagenodes will send the delete request to a piece Deleter,
which will process a "best-effort" delete asynchronously and return a
success message to the satellite.
There is a configurable number of max delete workers and a max delete
queue size.

On satellite, remove all references to free_bandwidth column in nodes table.
On storage node, remove references to AllocatedBandwidth and MinimumBandwidth and mark as deprecated.
Protobuf message, NodeCapacity, is left intact for backwards compatibility.
Once this is released to all satellites, we can drop the column from the DB.

When a storagenode begins to run low on capacity, we want to notify
the satellite before completely running out of space. To achieve this,
at the end of an upload request, the SN checks if its available space has
fallen below a certain threshold. If so, trigger a notification to the
satellites.
The new NotifyLowDisk method on the monitor chore is implemented using the
common/syn2.Cooldown type, which allows us to execute contact only once
within a given timeframe; avoiding hammering the satellites with requests.
This PR contains changes to the storagenode/contact package, namely moving
methods involving the actual satellite communication out of Chore and into
Service. This allows us to ping satellites from the monitor chore

Curently, storage nodes only report their capacity to satellites
once per hour. If a node fills up, it will fail all uploads until
the next contact cycle begins. With these changes, at the end of an
upload we check whether the MinimumDiskSpace threshold has been
passed. If so, trigger the monitor chore to update the node's
capacity, then trigger the contact chore to report the new
capacity to the satellites

this commit updates our monkit dependency to the v3 version where
it outputs in an influx style. this makes discovery much easier
as many tools are built to look at it this way.
graphite and rothko will suffer some due to no longer being a tree
based on dots. hopefully time will exist to update rothko to
index based on the new metric format.
it adds an influx output for the statreceiver so that we can
write to influxdb v1 or v2 directly.

this is to help protect against intentional or unintentional
slowloris style problems where a client keeps a tcp connection
alive but never sends any data. because grpc is great, we have
to spawn a separate goroutine for every read/write to the stream
so that we can return from the server handler to cancel it if
necessary. yep. really.
additionally, we update the rpcstatus package to do some stack
trace capture and add a Wrap method for the times where we want
to just use the existing error.
also fixes a number of TODOs where we attach status codes to the
returned errors in the endpoints.
