Description Clayton Coleman 2019-09-05 16:14:59 UTC 
Master scheduling is a key variant of cluster config that can lead to user failure and is also required to properly account for subscription information per cluster.

A metric on the cluster needs to report whether master schedulable is true and that needs to come back via telemetry.  The metric might look like

# masters are schedulable
cluster_master_schedulable 1
# masters are not schedulable
cluster_master_schedulable 0

Must be in 4.2 so we can properly count subscription data.

cluster-master-schedulable

Looking today I am able to see the cluster-master-schedulable metric on a running cluster (4.2.0-0.ci-2019-09-23-093016)
