Currently Cockroach migration test is the most heavy with regards to
schema changes. This causes other tests to time out. This adds an
alternate cockroach instance that is used for migration tests.

STORJ_POSTGRES_TEST naming was not consistent with STORJ_SIM_POSTGRES.
This allows to use STORJ_TEST_POSTGRES for clarity, it still has a
fallback to STORJ_POSTGRES_TEST.

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.
