Include prometheus- prefix for select monitoring charts

This adds the prometheus- prefix to the alertmanager,
kube-state-metrics and node exporter charts to reflect their
intended usage as part of a prometheus centric monitoring solution

This will imply a logical grouping of these components, similar to
their deployment in the osh-infra gates
