Report separate fault tolerances for each instance type in each region

Currently, a cluster's status reports the fault tolerance of the entire cluster, however when a single cluster is deployed using multi-region configuration a failure in the remote side will change the overall cluster's fault tolerance.

One could track the actual state of the cluster more easily if we tracked the fault tolerance of each instance type within each region. I.e. report the fault tolerance of storage processes in the primary region, storage processes in the remote region, log processes in the primary region, etc.

The issue names no files or tests. Start by tracing how cluster status currently calculates and reports fault tolerance, then determine how instance types and regions are represented. Done means status reports separate fault-tolerance values for each instance type in each region, including primary and remote regions.
