Prometheus: Update chart to support federation 

This updates the Prometheus chart to support federation. This
moves to defining the Prometheus configuration file via a template
in the values.yaml file instead of through raw yaml. This allows
for overriding the chart's default configuration wholesale, as
this would be required for a hierarchical federated setup. This
also strips out all of the default rules defined in the chart for
the same reason. There are example rules defined for the various
aspects of OSH's infrastructure in the prometheus/values_overrides
directory that are executed as part of the normal CI jobs. This
also adds a nonvoting federated-monitoring job that vets out the
ability to federate prometheus in a hierarchical fashion with
extremely basic overrides
