* 'two-dot-o' of https://git-wip-us.apache.org/repos/asf/incubator-usergrid:
  Add new ignore_error argument to /status end-point, which defaults to true and, also added Index health check to the /org/app/status end-point.
  There is now a new option on the /status end-point. If you specify "ignore_errors=false" the the /status end-point will return an HTTP 500 error if there is a problem connecting to Cassandra or of the query index is status RED for the management app.
  Oops
  Set shard and replica size at Index creation time and not client creation time.
