implement NoOpMigration for 0.30.0-alpha

[subodh1810]

We tried to release version 0.30.0-alpha of Airbyte without any Migration for version 0.30.0-alpha but the deployment started failing. This is because we rely on Automatic migration to make the database version with the new version value here
But the fact that we didnt introduce any migration, the automatic migration failed saying no migration found for version 0.30.0-alpha.

Because of that the db version was not updated with the new incoming version and as a result the check AirbyteVersion.isCompatible(airbyteVersion, airbyteDatabaseVersion.get()) here failed and the server didnt start up.

In order to solve it we introduced a NoOpMigration and tested it locally and it worked

I was checking something else and came across that the sourceType is not listed for this so decided to add it anyway as part of this PR

I think this will bite us in the future. Can we do something like this in ServerApp?

if (airbyteDatabaseVersion.isPresent() && isDatabaseVersionBehindAppVersion(airbyteVersion, airbyteDatabaseVersion.get())) {
   // run the migration
) else {
  jobPersistence.setVersion(airbyteVersion);
}
