Description of problem:

If you run katello-backup, it will save the postgres and mongo databases. For example, running "katello-backup --skip-pulp-content <path-to-backup-dir>" will result in a large backup that contains journal files and such.

Instead, katello-backup can use mongodump/mongoimport and pg_dump/pg_restore to back up and restore the two databases. This would make the backup files significantly smaller, and also easier to work with for debugging purposes.

NOTE: this would introduce an incompatibility between older backups and newer versions of katello-backup, so we would likely need a new option called '--small-db-dumps' or similar (not sure on best wording here).

Version-Release number of selected component (if applicable): 6.2.1
