Description

The current synced_followers metric reports all the forwarding followers, including non-voting ones.

We found it's useful to track how many servers are following leader in non-voting mode, so that we can identify issues like servers following but not issuing reconfig. This JIRA is going to add a separate metric to report the number of non-voting members.
