XD-813 Handle XD job destroy with BatchJobLocator/Registry
- When XD job is destroyed, the job name entry is removed from
  BatchJobLocator so that the Batch admin's launchable flag is set to false.
- Keep the 'isJobParameterIncrementable' flag in a separate table
  JOB_REGISTRY_INCREMENTABLES
  - Handle insert/update on subsequent job creation with same name
- Fixed BatchExecutionController's REST endpoints & jobName handling
- Moved HSQLServerBean class & registry schema sql out of dirt.plugins.job package
  as they only belong to XD Admin
