Fix tower_* modules **params kwargs (#40137)

* 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).
