4c1098e571 Redis: Update Redis package to last major version
Update the Redis dependency to use the last major production version.
The last version accepts a context parameter in all the network methods
so it allows us to pass it through them.

satellite/accounting/live: Use Redis client directly
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.

7999d24f81 all: use monkit v3
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.

4424697d7f satellite/accounting: refactor live accounting to hold current estimated totals
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
