Angus Salkeld edf86aeac2 Persist parent_resource_name and make sure it's available
We are persisting for a number of reasons:
- so we don't have to pass this through ever rpc call
- the API exposes parent_resource (currently always None as
  it is not persisted)

Closes-bug: #1438978

Tests for database migrations. This test case reads the configuration
file test_migrations.conf for database connection settings
to use in the tests. For each connection found in the config file,
the test case runs a series of test cases to ensure that migrations work
properly both upgrading and downgrading, and that no data loss occurs
if possible.
