bugzilla: add a rest api backend (usable with bugzilla 5.0+)

Add support for the bugzilla rest api documented at
 https://wiki.mozilla.org/Bugzilla:REST_API
and at
 https://bugzilla.readthedocs.io/en/latest/

This backend has the following benefits:
* It supports the bugzilla api keys so hgrc does not need to contain
  a user's bugzilla password
* Works with Mercurial's "hostfingerprints" support making handling
  bugzilla instances with self-signed certs easier
* Does not use xmlrpc ;-)

Adds configuration item 'apikey' in [bugzilla] section.

My major concern with these patches is if the approach to HTTP access
is the right way for an extension and if hooking into request object
and the overriding the get_method to perform PUT requests was a
sensible approach.
