Move runtime test resources into setup.cfg [extras]

testscenarios and testresources are only needed if you're using the
oslo.db testing fixtures downstream, otherwise you don't need this at
runtime in a deployment, so move them into the setup.cfg [extras] group.

If a consumer of oslo.db wants to use the db test fixtures then they
install oslo.db like 'sudo pip install oslo.db[fixtures]'.

This should trigger a major version bump for the library when it lands.

Closes-Bug: #1429233
