    Add ignore_none_type to config template

    It is sometimes useful to tell ConfigTemplateParser to write
    out options that are valueless and not suffixed with '=' or ':',
    such as when overriding a my.cnf.

    This commit adds the 'ignore_none_type' attribute to the config_template
    module. If this attribute is set to false, then valueless options will be
    written out to the resultant INI file as-is, without the '=' or ':' suffix.

    Conflicts:
     tests/test-config_template.yml
