For [chm]id, what is considered valid? Are the "common" names of these
valid, or do we have use some sort of unique ID instead?
It's certainly a good idea I think, and could be used to simplify a lot
of the frontend UI code.
For things like '/hosts/{hid}/metrics/{mid}/graph', how would various
graphing options be passed?
For /hosts/{hid}/metrics/{mid}/data, could that be expanded to return
LAST, MIN,MAX, AVERAGE (etc) values as well?
