Support leader readIndex

Hi all,

Raft algorithm allows to bypass raft log for read-only requests while still maintaining linearizability. This can benefit the read throughput of the entire system. 

I’ve submitted a proposal on supporting leader readIndex requests in Ratis. Please see issue https://issues.apache.org/jira/browse/RATIS-1557 <https://issues.apache.org/jira/browse/RATIS-1557> and proposal https://issues.apache.org/jira/secure/attachment/13047304/Proposal-Support%20leader%20readIndex.pdf <https://issues.apache.org/jira/secure/attachment/13047304/Proposal-Support%20leader%20readIndex.pdf> for more details. Please take a look. Any suggestions or advices would be really great!

Regards,
William Song
