Title:
  cloud-init does not take into consideration proxy when adding PPA's.

Status in cloud-init:
  Expired
Status in MAAS:
  Opinion

Bug description:
  In an environment behind a proxy, I've noticed that cloud-init fails
  to add a PPA because it fails to use the proxy to add such PPA. For
  example, in this environment we are adding a PPA APT source & defining
  the proxy for APT. See below:

  
  2017-06-08 19:50:26,126 - cc_apt_configure.py[DEBUG]: apt config: convert V2 to V3 format for keys 'apt_proxy'
  2017-06-08 19:50:26,126 - cc_apt_configure.py[DEBUG]: apt config: V1/2 and V3 format specified, preferring V3
  2017-06-08 19:50:26,126 - cc_apt_configure.py[DEBUG]: debconf_selections was not set in config
  2017-06-08 19:50:26,126 - cc_apt_configure.py[DEBUG]: handling apt config: {'sources': {'hardware_cert_3': {'source': 'ppa:hardware-certification/public'}}, 'proxy': 'http://10.90.90.1:8000/', 'preserve_sources_list': False, 'security': [{'uri': 'http://archive.ubuntu.com/ubuntu', 'arches': ['default']}], 'primary': [{'uri': 'http://archive.ubuntu.com/ubuntu', 'arches': ['default']}]}

  
  However, this fails to add with the following:

  
  2017-06-08 19:50:26,301 - util.py[DEBUG]: Running command ['add-apt-repository', 'ppa:hardware-certification/public'] with allowed return codes [0] (shell=False, capture=True)
  2017-06-08 19:50:37,110 - cc_apt_configure.py[ERROR]: add-apt-repository failed.
  Traceback (most recent call last):
    File "/usr/lib/python3/dist-packages/cloudinit/config/cc_apt_configure.py", line 609, in add_apt_sources
      util.subp(["add-apt-repository", source], target=target)
    File "/usr/lib/python3/dist-packages/cloudinit/util.py", line 1814, in subp
      cmd=args)
  cloudinit.util.ProcessExecutionError: Unexpected error while running command.
  Command: ['add-apt-repository', 'ppa:hardware-certification/public']
  Exit code: 1
  Reason: -
  Stdout: Cannot add PPA: 'ppa:~hardware-certification/ubuntu/public'.
          ERROR: '~hardware-certification' user or team does not exist.
  Stderr: -

  
  cloud-init should be using the provided proxy to attempt to add the PPA, provided that cloud-init is being told about a proxy that APT should use. In other words, since we are defining the proxy for APT, it makes sense we use the proxy to PPA add repositories as well.
