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

this commit introduces the reported_serials table. its purpose is
to allow for blind writes into it as nodes report in so that we have
minimal contention. in order to continue to accurately account for
used bandwidth, though, we cannot immediately add the settled amount.
if we did, we would have to give up on blind writes.
the table's primary key is structured precisely so that we can quickly
find expired orders and so that we maximally benefit from rocksdb
path prefix compression. we do this by rounding the expires at time
forward to the next day, effectively giving us storagenode petnames
for free. and since there's no secondary index or foreign key
constraints, this design should use significantly less space than
the current used_serials table while also reducing contention.
after inserting the orders into the table, we have a chore that
periodically consumes all of the expired orders in it and inserts
them into the existing rollups tables. this is as if we changed
the nodes to report as the order expired rather than as soon as
possible, so the belief in correctness of the refactor is higher.
since we are able to process large batches of orders (typically
a day's worth), we can use the code to maximally batch inserts into
the rollup tables to make inserts as friendly as possible to
cockroach.

everyone was importing it as dbx anyway. why should it be
named satellitedb? so yeah just pass the "-p dbx" flag.

Create a service for deleting pieces of storage nodes.
Currently the DeletePieces method returns after a success threshold,
completion or a timeout.
The end goal is to return when reaching the success threshold and
leaving the remaining goroutines running after DeletePieces method
returns and add a life cycle to the service that it waits for them when
it closes.
This is the first commit for ticket:

Revert because lib/pq has known issues with context cancellation.

the hope is that it is mostly interfering with itself, so this
will make it not do that (well, N api servers, but hopefully
that's not enough to cause it to have issues).

When an uplink requests an upload or download from the satellite we are trackig the
allocated bandwidth twice. The value in bucket_bandwidth_rollups is used
for project limits but the value in storagenode_bandwidth_rollups is not
used at all. We can increase the performance by removing it. Uplinks
will get a faster response from the satellite.

any database error doesn't mean the order wasn't found. for example
in cockroach it may say that the transaction is aborted. then what?
maybe we get big old row level deadlocks like we've observed? so
instead explicitly check for ErrNoRows to reject the order and bail
out otherwise. the surrounding logic will give it a retry.

turns out portable sed is hard: it has to work with both
linux and bsd sed, etc. instead, use a really really basic
bash script and a temporary file. this should be much less
likely to cause issues on a wide range of machines.

Transactions in our code that might need to work against CockroachDB
need to be retried in the event of a retryable error. The transaction
helper functions in dbutil do that automatically. I am changing this
code to use those helpers instead.

Disqualifies a node when the node fails to complete a graceful
exit.
Adds a new DisqualifyNode method to the overlay cache, since there
wasn't an existing method to disqualify a node but do nothing else
to its stats.
Adds checks to existing tests to make sure that a storage node that
fails a graceful exit is marked as disqualified in the overlay
cache.

crdb.ExecuteTx is great, but I don't think it will work right with
PostgreSQL. It works by way of cockroach savepoints, which allows
it to react to retryable errors, whereas tx.Commit() doesn't. But
I don't think PostgreSQL savepoints work exactly the same way. I'm not
100% sure, but it doesn't seem worth the risk.
So, I'm switching one case here to use the new dbutil.WithTx instead,
which will use crdb.ExecuteTx if appropriate. The other case doesn't
need a transaction at all.
