Add Liquibase to ACM runtime (Liquibase #3)

Add Liquibase to ACM runtime (Liquibase #3)

This is the minimal work to get Liquibase running in ACM runtime:

- Add Liquibase POM dependency.
- Add Liquibase changelogs running all SQL files.
- Pre-conditions are added for each set of changes, to allow upgrade
  from existing database created by DB-migrator to Liquibase.
- Minor changes for some SQL files to be compatible with H2 database,
  used in tests (otherwise maven build would fail).
- Disable hibernate ddl-auto so only Liquibase runs during tests.
