ubuntu-dev-tools needs better proxy support

[Jonathan Hogg]

I've just tried using the backportpackage command from behind a proxy. I had to manually go in and set proxy_info on calls in the following files/routines where httplib2.Http was being instantiated without any proxy information. I think someone needs to go through and address this issue globally, because if I accidentalyl hit two locations, odds are there's more!

ubuntutools/archive.py: def _donwload_dsc()
response, body = httplib2.Http().request(url)

ubuntutools/lp/lpapicache.py: login_anonymously()
self.__lp = LP.login_anonymously('ubuntu-dev-tools', service, version=api_version)

Status changed to 'Confirmed' because the bug affects multiple users.

are you running Bionic or Focal?

Oh wow I didn't notice this bug is from 2014. Not sure who added the recent confirmation, but at this point, this is probably a duplicate of bug 1887638
