Review comment:
@noblepaul what do you think of my changes in V2HttpCall? I figured out
how to compute both the templatized path and also the command verb. At this
particular spot, I wonder if it may be better to call getValidators to find the
command & path? At least getValidators appears cached.

Review comment:
@noblepaul when doing a GET request for V2, I found it to be a problem
that we add this stream that is empty, resulting in an exception at some point
about a blank Content-Type (as there is no content in the first place).
StandardRequestParser.parseParamsAndFillStreams checks !isPost and isV2 and
then calls this raw impl.
I could probably be more thorough here in detecting the presence of a
stream. Just because it's not a GET doesn't mean there is a stream! Weirdly,
req.getInputStream can return non-null for a GET which I observed in a test I
added in this PR.
