-----------------------------------------------------------------
[~ljain] Can you take a look at this change? I get the
testBasicAppendEntriesAsync to pass with this change.
Similar to randomized wait between min and max timeouts for leaderElection, the
heartbeat interval during that time will be randomized for (1, min), instead of
1 set practical minimum bound to 10.

> TestRaftAsyncWithGrpc#testBasicAppendEntriesAsync and other tests fail if the
> initial minTimeout is 0 then the server can trigger a leader election much
> more frequently because the heartbeat interval is still at minTimeoutMs/2
