David Shrewsbury 2b7496c0ee Compress database backups.
Fixes bug 951600.

The update_gerrit_users.py script creates a database backup
everytime it runs. This change compresses the backups as they
are being made and adds a cron job that will remove backups that
are 30 days or older. Current backups will need to be manually
compressed.
