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.

59d06644b9 private/migrate: switch to tagsql
Also added temporary types withRebind and withTagTx,
which will be later removed. Currently they help to avoid
changing the whole codebase at the same time.

64fb2d3d2f Revert "dbutil: statically require all databases accesses to use contexts"
This reverts commit 8e242cd012.

Revert because lib/pq has known issues with context cancellation.
These issues need to be resolved before these changes can be merged.

8e242cd012 dbutil: statically require all databases accesses to use contexts
this will allow for some nice runtime analysis down the road.
also, this allows for wrapping database handles in a way that
can interact with these contexts

requires https://review.dev.storj.io/c/storj/dbx/+/514

df9e53ea0b private: ensure we don't eat the underlying error
When error is formatted using %v it's not possible to check
whether the error was caused by a context cancellation.

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.

f41d440944 all: reduce number of log messages
Remove starting up messages from peers. We expect all of them to start,
if they don't, then they should return an error why they don't start.
The only informative message is when a service is disabled.

When doing initial database setup then each migration step isn't
informative, hence print only a single line with the final version.

Also use shorter log scopes.
