Use exponential backoff to query leader. (#4313)

Browse Source 
`topology.Leader()` was using a backoff that typically
resulted in at least a 5s delay when initially starting
a master and raft server. This changes the backoff
algorithm to use exponential backoff starting with 100ms
and waiting up to 20s for leader selection.
