Title:
  template for resolv.conf doesn't work if no options are provided

Status in Init scripts for use on cloud images:
  Fix Released

Bug description:
  When using the plugin for configuring resolv.conf it will always fail
  if no options are provided in the config.

  The reason is the template includes the check [1]:

  #if $varExists('options') or $varExists('flags')

  The flags variable is set to an empty list in the generate_resolv_conf
  function [2] before the template is rendered and $varExists('flags')
  will always return true because of this. Because I know the variable
  will always exist and an empty list resolves as false in python I was
  able to work around this bug by changing the line in the template to
  read:

  #if $varExists('options') or $flags

  The plugin is now handling my configs properly and generating a valid
  resolv.conf on the systems.
