tests form changine engine from local to remote db added, some fixes

- 2 new containers added in containers-deploy, that are used for migration
- new engine added to engine-cleanup
- engine-deploy-local-db added
- test of ovirt-engine-local-to-remote-db added to test-*
- get ip of engine and database from proper variables in ovirt-engine-local-to-remote-db
- reset added to ovirt-engine-local-to-remote-db
