Get rid of httplib2, use urllib3 instead

httplib2 has been abandonned by its author [1] and is less going
to be updated and maintained than urllib3. So, let's replace httplib2
with urllib3.

Note that this patch mostly rework the unit tests.

I removed the files `tempest.tests.fake_identity` and
`tempest.tests.fake_http` to use their `tempest.tests.lib` counterpart.

Also, I tried to "encapsulated" HTTP calls and use
`tempest/lib/common/http.py` everywhere so that we only import
urllib3 once. This makes us not so dependent on a specific HTTP
library.
