Description

A "git"-style shell script that allows a single point of entry to manage and monitor any of the bigtop upstream systems.
Something like mvn or git command. This will introduce something to
learn at first but it adds value to start/stop/access help for all systems in
a consistent way. It can also shield some changes that happens with
upstream systems. Instead of dealing with some many <XXX>_HOME, we can have one BIGTOP_HOME environment variable.

Proposed on bigtop email lists, and presented the attached slides during the hackathon.
