Title:
  Unable to fetch git repos via python subprocess with proxy configured
  git 2.17.0-1ubuntu1

Status in git package in Ubuntu:
  Invalid
Status in linux package in Ubuntu:
  Fix Released

Bug description:
  All the tests that need to fetch a git repo for testing failed with error message like:
      CmdError: Command <git clone https://github.com/tytso/xfstests-bld> failed, rc=128, Command returned non-zero exit status
      * Command:
          git clone https://github.com/tytso/xfstests-bld
      Exit status: 128
      Duration: 0.254368066788

      stderr:
      Cloning into 'xfstests-bld'...
      fatal: unable to access 'https://github.com/tytso/xfstests-bld/': gnutls_handshake() failed: An unexpected TLS packet was received.

  Step to reproduce:
    1. Deploy a Bionic system and install the python-minimal package
    2. Run the following python code:
   import subprocess
   import os

   proxysets = [{'addr': 'squid.internal', 'desc': 'Running in the Canonical CI environment'},
                {'addr': '91.189.89.216', 'desc': 'Running in the Canonical enablement environment'},
                {'addr': '10.245.64.1', 'desc': 'Running in the Canonical enablement environment'}]
  for proxy in proxysets:
          cmd = ['nc', '-w' ,'2', proxy['addr'], '3128']
          try:
              subprocess.check_call(cmd)
              print proxy['desc']
              os.environ['https_proxy'] = 'https://' + proxy['addr'] + ':3128'
              break
          except:
              pass

   subprocess.check_call(['git', 'clone', 'https://github.com/tytso/xfstests-bld'])
     4. Update the git package from 2.15.1-1ubuntu2 to 2.17.0-1ubuntu1
     5. Remove the xfstests-bld dir and try step 3 again

  Result:
    * Step 1 - 3 with git 2.15.1 will work, but you will see the error message with git updated to 2.17.0 (this code works without proxy configured)
