keepalive: honor urllib2 style get_method overrides

In urllib2 docs and discussions it can be found that in order
to make a request other than GET or POST the get_method of a
Request object can be overriden. Make Mercurial's internal
version of this honor the return value of get_method.

Please see the followup patch to the bugzilla extension for
the reason for this change. Marking RFC because I'm not entirely
sure this is the right way make the HTTP requests.
