Configure placement DB context manager for nova-manage/status
The create_incomplete_consumers online data migration was added in
Rocky via change Id609789ef6b4a4c745550cde80dd49cabe03869a. That
relies on hitting some tables in the API (or placement) database.
The DB API code for that migration relies on a placement context
manager which looks like it was regressed with change
I2fff528060ec52a4a2e26a6484bdf18359b95f77 (also in Rocky). This
results in a DB error trying to query the projects table but
because of a generic try/except in _run_migration, the failure
was missed in CI testing.
Similarly, the nova-status upgrade check "_check_resource_providers"
routine also uses the placement DB API context manager to count the
number of compute resource providers in the API (or placement) DB,
which is returning 0 because it's not using the proper DB connection.
This was not caught in the nova-status CLI tests because they use
the DatabaseFixture which *does* configure the global placement DB
API context manager.
This adds the configuration of the global placement DB API context
manager so we can properly query the placement-related tables.
The blanket problematic try/except from _run_migration is left
as-is in this change but will be addressed in a separate patch.
Integration testing of this fix is being performed with devstack:
