The master-is-stable indicator will retrieve useful information
regarding the discovery. This will be useful even if the local
cluster state is not recovered.

We currently do not evaluate the instance-has-master indicator
if the cluster state is not recovered, but we should remove this
constraint once master-is-stable is merged
