Public bug reported:

While users that modify the config file should remove any stages they do
not want executed failing to do so results in a traceback:

Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/cloudinit/cmd/main.py", line 638, in status_wrapper
    ret = functor(name, args)
  File "/usr/lib/python2.7/site-packages/cloudinit/cmd/main.py", line 416, in main_init
    return (init.datasource, run_module_section(mods, name, name))
  File "/usr/lib/python2.7/site-packages/cloudinit/cmd/main.py", line 107, in run_module_section
    (which_ran, failures) = mods.run_section(full_section_name)
  File "/usr/lib/python2.7/site-packages/cloudinit/stages.py", line 817, in run_section
    raw_mods = self._read_modules(section_name)
  File "/usr/lib/python2.7/site-packages/cloudinit/stages.py", line 700, in _read_modules
    for item in cfg_mods:
TypeError: 'NoneType' object is not iterable

Rather than complaining cloud-init should handle this gracefully and
just skip the stage and do nothing.
