[Proposal] Make the default Unifier ThreadLocal with the downstream operator

Hi All,

Unifier's are deployed as CONTAINER_LOCAL with the downstream operator(
except in the corner case of Mx1 ).  Default Unifiers are essentially doing
buffer to buffer copy, so instead it should be THREAD_LOCAL to improve the
performance.

Let me know your thoughts on this.

Thanks

+1. Makes sense. Do need to allow users to override if they want.
