* Add cleaning function to handle **params
The cleaning function is only added to tower modules which pass a `**params`
argument as an unpacked dictionnary to the tower-cli method calls.
Fix#39745
* Remove previous code added only for tower_role
In 872a7b4, the `update_resources` function was modified so that it would clear unwanted
parameters. However, this behaviour is desired for other modules too, modified in
another commit. (see tower_clean_params).
* Ansible Tower job_launch module
* Added RETURN documentation and fixed import locations
* remove superfluos required attributes, make tags a list, and fix some typos
* only join tags if they are actually a list
* use isinstance instead of type, cleanup imports
