Method to query ElasticSearch for a specific set of browbeat_uuids and
compare the metadata to determine if there are differences.
This work will also tell the user if a option or value is missing.
Eventually, I would like to see us query Elastic for collectd data to
see if there has been CPU/Memory/DiskIO increases during a specific
Browbeat run -- this is a longer-term goal.
Example of this :
