Kevin Smith 2e89eb368a Stx-monitor: add setup script flexibility
Move the beats setup scripts to the values files so they can be
overridden.

Additionally, set the maxUnavailable parameter for the elasticsearch
charts so that a maximum of one pod at a time will be down
when the application is re-applied or upgraded.
