Running status in fdbcli prints the number of processes and machines, but not the number of zones. The number of zones is relevant in calculating the fault tolerance of the system, and having this number be displayed could provide some hints when fault tolerance is not what is expected.

It's possible that we could even break up this number into the count by something roughly like process class, given that we care how many zones we have available to logs, coordinators, etc, but that may be more clutter than it's worth.
