      Description

      We don't instrument amILeader calls right now. We have a large cluster where we find that the overseer isn't processing operations as fast as it should. Since all operations are pretty fast even at the 99th percentile, the slowdown might be due to amILeader and the ZK update calls.

      Let's start measuring those as well.

        This patch measures:

        • amILeader calls in Overseer and OverseerCollectionProcessor
        • Cluster state updates in Overseer

        Added a simple test as well. I'll commit soon.
