-----------------------------------------------------------
[~hitesh], Is this still valid now ? sending V_INIT to downstream after vertex
is initialized make more sense and will make the state machine easy to
understand. I think we should we either fix this or rename
numInitedSourceVertices to numInitStartedSourceVertices, otherwise it is a
little confusing.

> Current impl sends V_INIT event even though the vertex may be initializing
> itself. Downstream vertices may be dependent on initialized info of upstream.
> Related fix in recovery for TEZ-998 should be reverted as part of this jira.
