074649835b satellite/satellitedb: add some docs and improve some snapshots
This attempts to add a README.md to help create consistent migrations
that maximize our test coverage and do not include unnecessary
statements.

It also adds a feature to have an `-- OLD DATA --` section as well
as a `-- NEW DATA --` section so that we can fix mistakes made in
previous snapshots (like a row that was forgotten to be added when a
table was created) without editing them going forward.

8d87a6efc9 cockroachutil/driver: handle retryable errors returned from Next
This will only work if retryable errors are returned on the first
call to Next. Otherwise if they're returned later, we will need
deeper changes at the application code level throughout the
codebase 😬👎

85c45cd56f private/dbutil/pgtest: support multiple databases for testing
Currently Cockroach isn't performant for concurrent database setup and
tear-down. Instead of a single instance allow setting multiple potential
connection strings and let the tests pick one connection string
randomly.

This improves test duration by ~10 minutes.

While we are at significantly changing how pgtest works, introduce
helper PickPostgres and PickCockroach for selecting the database to
reduce code duplications in multiple places.

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.

d20db90cff private/dbutil/txutil: create new transactions for retries
it was noticed that if you had a long lived transaction A that
was blocking some other transaction B and A was being aborted
due to retriable errors, then transaction B was never given
priority. this was due to using savepoints to do lightweight
retries.

this behavior was problematic becaue we had some queries blocked
for over 16 hours, so this commit addresses the issue with two
prongs:

    1. bound the amount of time we will retry a transaction
    2. create new transactions when a retry is needed

the first ensures that we never wait for 16 hours, and the value
chosen is 10 minutes. that should be long enough for an ample
amount of retries for small queries, and huge queries probably
shouldn't be retried, even if possible: it's more preferrable to
find a way to make them smaller.

the second ensures that even in the case of retries, queries that
are blocked on the aborted transaction gain priority to run.

between those two changes, the maximum stall time due to retries
should be bounded to around 10 minutes.

5a1838bc28 private/dbutil: retry single statements on cockroachdb
This ought to make it so that all single statements (Exec- or Query-) on
a CockroachDB backend will get retried as necessary. As there is no need
for savepoints to be allocated or released in this case, there is no
round-trip overhead except when statements actually do need to be
retried.

fd84fa6316 private/dbutil: rollback pending transactions on panic
We don't do a lot of panicking in our main code, so hopefully this won't
matter much, but we /do/ call panic a lot in our tests (t.Fatal,
require.NoError, etc). And when that happens, we need pending
transactions to be aborted or we can get into a deadlock situation when
something else tries to /Close/ that connection.

0c88a7b475 private/migrate: use transactional helpers and not Begin()
This code needs to work against cockroachDB, so transactions must be retried
when a retryable error is returned. This change puts migrate
transactions into the dbutil.WithTx transactional helpers to achieve
this in the easiest way.

6231842422 private/dbutil: add WithTx transaction helpers
These helpers will work similar to the WithTx method we have added to
our dbx.DB instances, but it will use crdb.ExecuteTx or crdb.ExecuteInTx
when the backend is CockroachDB, so that transactions are retried
correctly.

Anything that uses transactions and might need to work against
CockroachDB needs to handle "RetriableError" from cockroachdb by
restarting the transaction. This will probably be a large pain if not
using these helpers or something very like them.

Subsequent changes will undertake transforming all db-transaction uses
in satellite code so that they are cockroach-safe.

48da8baab5 storj-sim: work with cockroach:// urls for satellite databases
for storj-sim to work, we need to avoid schemas in cockroach urls
so we have storj-sim create namespaced databases instead of schemas
and we have the migrate command create the database in the same way
that it would create a schema for postgres. then it works!

a follow up commit will move the creation of the database/schemas
into storj-sim's setup step so that we can avoid doing these icky
creations during normal migration calls. it will also make the
pointerdb have an explicit call to migrate instead of just doing
it every time it's opened.
