CRDB doesn't like large deletes. While testing in the POC environment we found that deletes on the serial_numbers table could take hours. This change limits deletes to 1000 at a time (configurable) to avoid blocking other queries.

With the new phase 3 order submission, orders can be added to the
storage and bandwidth rollup tables at timestamps before the most recent
rollup was run. This change shifts the start time of each new rollup
window to account for any unexpired orders that might have been added
since the previous rollup.
A satellitedb migration is necessary to allow upserts in the
accounting_rollups table when entries with identical node_ids and
start_times are inserted.

It turns out we need to make 2 more changes in order for the new order submission phase 3 to get deployed.
This PR makes 2 changes:
1) when the rollup service deletes tallies, we now keep tallies around until orders expire (vs 1 day like before).
2) the reported rollup chore will now write the storagenode_bandwidth_rollups to a new table _phase2 as an intermediary step so it doesn't conflict with phase 3 order settlement.
These changes need to be deployed for 2 days before we can turn on phase 3 of the new orders settlement workflow.

Doing it at the ProcessOrders level was insufficient: the endpoints
make multiple database calls. It was a misguided attempt to only
have one spot enter the semaphore. By putting it in the endpoint
we can not only be sure that the concurrency is correctly limited
but it can be configurable easily.

measurement and tracking.

What:
Use the github.com/jackc/pgx postgresql driver in place of
github.com/lib/pq.
Why:
github.com/lib/pq has some problems with error handling and context
cancellations (i.e. it might even issue queries or DML statements more
than once! see https://github.com/lib/pq/issues/939). The
github.com/jackx/pgx library appears not to have these problems, and
also appears to be better engineered and implemented (in particular, it
doesn't use "exceptions by panic"). It should also give us some
performance improvements in some cases, and even more so if we can use
it directly instead of going through the database/sql layer.

This ensures that rows are closed to avoid leaks.
Also verifies that Err() is called, to ensure that no

this way we don't have to do 2 steps, and by using the ctid, postgres
is going to do two very efficient prefix scans.

also remove the continuation support from the queue, otherwise
we may end up sequential scanning the entire table to get
a few rows at the end.
then, in the core, instead of looping both to get a big enough
batch inside of the queue, as well as outside of it to ensure
we consume the whole queue, just get a single batch at a time.
also, make the queue size configurable because we'll need to
do some tuning in production.

by doing an indexed anti-join we're able to reduce the time to
select the pending orders by over 10x on postgres. this should
help us process pending orders much more quickly.
it probably won't do as good a job on cockroach because it does
not do an indexed anti-join and instead does a hash join after
scanning the entire consumed serials table. we should either
remove orders entirely or try to make that more efficient
when necessary.

This change adds two new tables to process orders as fast as we used
to but in an asynchronous manner and with hopefully less storage
usage. This should help scale on cockroach, but limits us to one
worker. It lays the groundwork for the order processing pipeline to
be queue rather than database driven.
For more details, see the added fast billing changes blueprint.
It also fixes the orders db so that all the timestamps that are
passed to columns that do not contain a time zone are converted to
UTC at the last possible opportunity, making it less likely to use
the APIs incorrectly. We really should migrate to include timezones
on all of our timestamp columns.

A uuid.UUID is an array of bytes, and slicing it refers to the
underlying value, much like taking the address. Because range
in Go reuses the same value for every loop iteration, this means
that later iterations would overwrite earlier stored project
ids. We fix that by making a copy of the value before slicing it
for every loop iteration.

Since incoming times may be in any time zone, and we want the output
to be in UTC and for them to have 00:00:00 hours, minutes and seconds
we first convert the incoming timestamp to UTC before doing the
truncate to the day and adding a day.
Because the old code always returned a timestamp that was in the
future, this is just for efficiency.

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.

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.

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

Backstory: I needed a better way to pass around information about the
underlying driver and implementation to all the various db-using things
in satellitedb (at least until some new "cockroach driver" support makes
it to DBX). After hitting a few dead ends, I decided I wanted to have a
type that could act like a *dbx.DB but which would also carry
information about the implementation, etc. Then I could pass around that
type to all the things in satellitedb that previously wanted *dbx.DB.
But then I realized that *satellitedb.DB was, essentially, exactly that
already.
One thing that might have kept *satellitedb.DB from being directly
usable was that embedding a *dbx.DB inside it would make a lot of dbx
methods publicly available on a *satellitedb.DB instance that previously
were nicely encapsulated and hidden. But after a quick look, I realized
that _nothing_ outside of satellite/satellitedb even needs to use
satellitedb.DB at all. It didn't even need to be exported, except for
some trivially-replaceable code in migrate_postgres_test.go. And once
I made it unexported, any concerns about exposing new methods on it were
entirely moot.
So I have here changed the exported *satellitedb.DB type into the
unexported *satellitedb.satelliteDB type, and I have changed all the
places here that wanted raw dbx.DB handles to use this new type instead.
Now they can just take a gander at the implementation member on it and
know all they need to know about the underlying database.
This will make it possible for some other pending code here to
differentiate between postgres and cockroach backends.
