Tear httplib2 out of google-cloud

[dhermes]

I plan to tackle this soon-ish.

This is so we can move to a better-maintained (or allow BYO) transport layer.

This should now be possible since oauth2client has been replaced with google-auth.

google.cloud.streaming needs fixin' first (I seem to recall @jonparrott volunteering for that one, but can't confirm it because our chat history gets deleted!)

[theacodes]

Have we a bug for streaming?

My chat history gets deleted to prevent me from volunteering for dumb things.

[dhermes]

I don't think so, it's part of the "ditch httplib2 bug"

@dhermes @jonparrott is google_auth_httplib2.py what should be used instead of directly using httplib2?
