If the type of an argument is not set, ansible defaults to treating it
as a string. As such it gets run through a validator that converts the
value to a string via str().
In the case of 'value' being null, or perhaps a dict or list that
contained null, the conversion via str() would cause the python native
None to be passed to this module, which when parsed through
yaml.safe_load() in parse_value(), would return the string 'None'.
To fix this, we set the type of 'value' to a noop validator, as the type
may vary and we don't want ansible to perform any conversion.
