[DISCUSS] Apache Ratis 0.4.0 release

[Mukul Kumar Singh]

Hi,

It has been a while since our last Ratis release.
We have around 50 commits after our latest 0.3.0 release.

How about we start the process for a new Ratis release (0.4.0).
We can create a new 0.4.0 branch and change trunk to 0.5.0.

Thanks,
Mukul
