  - Merge "Ansible: fix lowercasing issue with ConfigParser"
  - Ansible: fix lowercasing issue with ConfigParser
    
    by default ConfigParser will lowercase everything,
    unless you override optionxform.
    
    also sort key value in inventory line for consistency
    
    https://docs.python.org/3/library/configparser.html#configparser.ConfigParser.optionxform
    
    Transforms the option name option as found in an input file or as passed in by
    client code to the form that should be used in the internal structures. The
    default implementation returns a lower-case version of option; subclasses may
    override this or client code can set an attribute of this name on instances to
    affect this behavior.
    
    You don’t need to subclass the parser to use this method, you can also set it
    on an instance, to a function that takes a string argument and returns a
    string. Setting it to str, for example, would make option names case sensitive:
    
    cfgparser = ConfigParser()
    cfgparser.optionxform = str
    
    Note that when reading configuration files, whitespace around the option names
    is stripped before optionxform() is called.
