Need monitoring solution

[RSTJNII]

We need to come up with a outside monitoring solution (preferably Rackspace MaaS) to verify that backups are running as expected. This should be as independent of the target server as possible.

https://github.com/racker/rackspace-monitoring-agent-plugins-contrib/blob/master/cloudbackup_mon.sh was suggested but failed initial testing. As such it was left out of the v1.0.0 refactor.

That plugin would probably be much neater as a Python script instead of Bash. That script also expects the API key on the command line, if is is to be refactored for this cookbook we should make it parse /etc/driveclient/run_backup.conf.yaml which should contain all the data it needs to run without arguments. That would make for a cleaner solution.
