Dynamically collect secrets for backup & restore roles

- This prevents us from overwriting vars unintentionally at restore time
  - This will make it easier to add secrets to be backed up in the future
  - Add generated secret names to awx spec backup
  - Fail early if secret status doesn't exist
  - Skip if secret is not in spec for non-generated secrets
  - Secret values must be b64 decoded before secret is created
  - Cleanup temp files
