Previously there was no realtime administration of the storage usage
during copies. Now there is.

Satellite caches the project bandwidth in Redis when it doesn't have it
because was not set or the key expired, however, it doesn't perform the
check and set if not exists in a transaction. It also uses the increase
function which increases the value if it exists otherwise it sets it.
This provokes that multiple concurrent request to the same project may
increase the total project by multiples of the bandwidth usage
registered in the database rather than setting it because they may check
if the key exists before any other has executed the increase and then
the first one executing it will set the value but the others will
increased causing that Redis has a wrong bandwidth usage value which is
N magnitude of the real one and making the satellite to deny the
downloading if it surpasses the project limit.
This commit changes the "update"" project bandwidth usage by an "insert"
but using a Redis function that only sets the value if the key doesn't
exists for solving the increase issue but also not overriding the value
due to may contain updates of other downloading requests which aren't
already registered in the DB.

modify tally to calculate how we need to update segments in the live accounting
cache with UpdateProjectSegmentUsage method. adjust accounting.ExceedsUploadLimits
to use only cache for segment validation, if cache returns 0 or key not found then
we shouldn't reject such project as its possible that we won't have this value before first object iteration

Initialy we wanted to put segment usage into cache values retrieved
directly from metabase but it cause performance issues. Now we
will be collecting segment usage from tally object loop and those
values will be put into a cache but becuse we cannot get those values
on demand we shouldn't expire cache value at all because objects
loop requires sustencial amount of time to be executed.

For better performance we should use AOST for getting
data where being up to data it not very crucial. We don't
care about small differences for segment limit calculation.

We had two problems here. First was how we were handling
errors message from GetProjectSegmentUsage. We were always
returning error, even for ErrKeyNotFound which should be used
to refresh value in cache and not propagated out of method.
Second, we were using wrong value to update cache. We used
current value from cache which obviously it's not what we intend.

We want to be able to limit the number of segments per project for users.
To limit this we need to check limit value associated with project
and value of used segments already in BeginMoveObject, BeginMoveSegment
and increment cache segments usage after each CommitSegment call.

We want to set maximum number of segments per project. This change will
add functionality to get number of segments currently used by project.
To avoid often DB calls segment cound will be cached and refreshed every
few minutes.

Replace GetProjectAllocatedBandwidth by GetProjectBandwidth which calculates
used bandwidth from allocated and settled bandwidth recorded in the
project_bandwidth_daily_rollups table.
For each day in the month, if the allocated bandwidth is expired, it uses the
settled bandwidth for computing used bandwidth.

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.

We have to adapt the live accounting to allow the packages that use it
to differentiate about errors for being able to ignore them and make our
satellite resilient to Redis downtime.
For differentiating errors we should make changes in the live accounting
but also in the storage/redis.Client, however, we may need to do some
dirty workarounds or break other parts of the implementation that
depends on it.
On the other hand we want to get rid of the storage/redis.Client because
it has more functionality that the one that we are using and some
process has been started to remove it.
Hence, we have refactored the live accounting to directly use the Redis
client library for later on (in a future commit) adapt the satellite for
being resilient to Redis downtime.
Last but not least, a test for expired bandwidth keys have been added
and with it a bug was spotted and fix it.

This PR adds the following items:
1) an in-memory read-only cache thats stores project limit info for projectIDs
This cache is stored in-memory since this is expected to be a small amount of data. In this implementation we are only storing in the cache projects that have been accessed. Currently for the largest Satellite (eu-west) there is about 4500 total projects. So storing the storage limit (int64) and the bandwidth limit (int64), this would end up being about 200kb (including the 32 byte project ID) if all 4500 projectIDs were in the cache. So this all fits in memory for the time being. At some point it may not as usage grows, but that seems years out.
The cache is a read only cache. When requests come in to upload/download a file, we will read from the cache what the current limits are for that project. If the cache does not contain the projectID, it will get the info from the database (satellitedb project table), then add it to the cache.
The only time the values in the cache are modified is when either a) the project ID is not in the cache, or b) the item in the cache has expired (default 10mins), then the data gets refreshed out of the database. This occurs by default every 10 mins. This means that if we update the usage limits in the database, that change might not show up in the cache for 10 mins which mean it will not be reflected to limit end users uploading/downloading files for that time period..

Currently we have no way to actually set one
of the following limits to 0 (meaning not usable):
- maxBuckets
- usageLimit
- bandwidthLimit
With having the field nullable,
NULL corresponds to the global default,
0 now actually 0 and
a set value determines a custom limit.

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.

live accounting used to be a cache to store writes before they are picked up during
the tally iteration, after which the cache is cleared. This created a window in which
users could potentially exceed the storage limit. This PR refactors live accounting to
hold current estimations of space used per project. This should also reduce DB load
since we no longer need to query the satellite DB when checking space used for limiting.
The mechanism by which the new live accounting system works is as follows:
During the upload of any segment, the size of that segment is added to its respective
project total in live accounting. At the beginning of the tally iteration we record
the current values in live accounting as `initialLiveTotals`. At the end of the tally
iteration we again record the current totals in live accounting as `latestLiveTotals`.
The metainfo loop observer in tally allows us to get the project totals from what it
observed in metainfo DB which are stored in `tallyProjectTotals`. However, for any
particular segment uploaded during the metainfo loop, the observer may or may not
have seen it. Thus, we take half of the difference between `latestLiveTotals` and
`initialLiveTotals`, and add that to the total that was found during tally and set that
as the new live accounting total.
Initially, live accounting was storing the total stored amount across all nodes rather than
the segment size, which is inconsistent with how we record amounts stored in the project
accounting DB, so we have refactored live accounting to record segment size
