accept tag values in the body as well as URL
accept tag values in the body as well as URL

The JS client passes arguments to the PUT call in the URL so we need
the tags argument to the put() method. The python client passes
arguments encoded in the body of the request, so we need the body
argument. Merge the two sets of values so that inside the function we
only have to process one list.
