Consolidate status API information on /status

[zalegrala]

Currently there are a few endpoints that convey information about the configuration and status of the running instance. As part of #938 and #632, we now have a /status end point that is ready to accept a query parameter to organize all the data about status.

The following may serve as a guide as to what gets moved to the /status endpoint.

/status?config
/status?runtime_config
/status?services
/status?endpoints <-- currently implemented

This could mean we reduce the number of endpoints we have to convey status information, and still allow users to ask for only the portion of the status that is of interest.
