Ensure credentials are automatically backed up

[seanshahkarami]

We need to make sure critical pieces of credential information are automatically backed up and that we're able to restore the state of beehive from it.

For reference, I have a list of the credentials in use here: https://github.com/waggle-sensor/waggle/wiki/Credentials-Overview

I can't emphasis enough how crucial this is...

This is important enough that until this is in effect, we should probably hold off on major redesign work on beehive in case something goes wrong.

I started addressing the backup step with this: https://github.com/waggle-sensor/ansible/blob/master/beehive/backup-credentials.yml

We just need a secure, reliable place to store all of this.

I went ahead and included MySQL in this. Currently, all ssh keys, all TLS/SSL and all MySQL tables are archived and backed up using the backup-credentials playbook.

@geeklair @rajeshxsankaran I just need approval of a secure, reliable location to close this.

I have a snapshotting job putting a archived copy of the credentials in /digital/backup as backup-%Y%m%d.tar.gz.
