Clear local logged stores if input checkpoints are empty

[ajothomas]

Symptom:
If an external utility attempts to reset a job's state by clearing backups and checkpoints, the local state still remains. We need to clear the local rocksdb state of stateful jobs, if the inputs checkpoints don't exist.

Changes:

• This PR checks if the input checkpoints for a container are empty and clears the local logged stores if they are.

Tests:

• ./gradlew build
• Added unit test in TestContainerStorageManager to verify that stores are deleted from logged store dir on empty checkpoints
• Tested with a test job which had its checkpoints and backup cleared.
