"""Create a new label.
There are two types of label creation: isolatedly creating a new label and creating a new label under
a job template. Here the two types are discriminated by whether to provide --job-template option.
Fields in the resource's `identity` tuple are used for a lookup; if a match is found, then no-op (unless
`force_on_exists` is set) but do not fail (unless `fail_on_found` is set).
=====API DOCS=====
Create a label.
:param job_template: Primary key or name of the job template for the created label to associate to.
:type job_template: str
:param fail_on_found: Flag that if set, the operation fails if an object matching the unique criteria
already exists.
:type fail_on_found: bool
:param force_on_exists: Flag that if set, then if a match is found on unique fields, other fields will
be updated to the provided values.; If unset, a match causes the request to be
a no-op.
:type force_on_exists: bool
:param `**kwargs`: Keyword arguments which, all together, will be used as POST body to create the
resource object.
:returns: A dictionary combining the JSON output of the created resource, as well as two extra fields:
"changed", a flag indicating if the resource is created successfully; "id", an integer which
is the primary key of the created object.
:rtype: dict
:raises tower_cli.exceptions.TowerCLIError: When the label already exists and ``fail_on_found`` flag is on.
