The purpose of this function is to be used to validate any variables created in
a play to be valid Python identifiers and to not conflict with Python keywords
to prevent unexpected behavior. Since Python 2 and Python 3 differ in what
a valid identifier is, this function unifies the validation so playbooks are
portable between the two. The following changes were made:

* disallow non-ascii characters (Python 3 allows for them as opposed to Python 2)
    * True, False and None are reserved keywords (these are reserved keywords
      on Python 3 as opposed to Python 2)

:arg ident: A text string of identifier to check. Note: It is callers
    responsibility to convert ident to text if it is not already.
