[Bug 1578351] Re: mitaka ksclient fails to connect to v6 keystone

[Martin Pitt]

Hello Edward, or anyone else affected,

Accepted python-urllib3 into xenial-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/python-
urllib3/1.13.1-2ubuntu0.16.04.1 in a few hours, and then in the
-proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

Bug description:
  [Impact]
  urllib3 is not stripping [] from IPv6 URL's, resulting in double square brackets which breaks connectivity to targets.

  [Test Case]
  <relying on Ed for actual testing>
  Deploy OpenStack with IPv6 preferred; keystone service is unable to self configure as extra brackets are inserted to the URL hostname resulting in failed connections.

  [Regression Potential]
  Change in behaviour was reverted upstream; regression potential minimal.
