* Add script to update Azure SQL firewall rules from GitHub meta API
* Update state.azure.sql test to use unique DB names
- Add use of `databaseName` metadata to state.azure.sql test.
- Add dynamic generation of test `databaseName` to conformance.yml to
avoid multiple test instances from racing.
- Add wait before clean-up of Azure SQL DB instance in conformance.yml
to prevent test flakiness and accumulation of undeleted DBs.
- Remove dynamic Azure SQL firewall rule injection from conformance.yml.
- The workflow relies on IPs used by GitHub Actions to be provisioned
in the firewall rules already.
- Update documentation for managing Azure SQL and testing instructions.
