> Some things can be improved:
> * throws Exception declaration can be removed from
> LeveldbRMStateStore.initInternal methodÂ
> * key variable is redundant in LeveldbRMStateStore.dbStoreVersion
> * try can use automatic Resource management in
> LeveldbRMStateStore.loadReservationState/loadRMDTSecretManagerKeys/loadRMDTSecretManagerTokens/loadRMApps/...
> etc
> * there were some methods which were copied to LeveldbConfigurationStore
> (ie: openDatabase, storeVersion, loadVersion, CompactionTimerClass nested
> class), a helper class could be created to reduce the duplicated code
> * Any other cleanup
