Modhelper improvements (#1480)

* Improvements in module_helper

- added `ModuleHelperException` to handle problems specific to ModuleHelper
- updated `module_fails_on_exception` for `ModuleHelperException`
- `StateMixin`: composed names of state methods are now calculated instead of fixed.
- `CmdMixin`: added `run_command_fixed_options` to pass some parameters on every call

* Improvements in module_helper

- Named deprecations: ability to declare a `dict` of deprecations indexed by names, allowing module maintainer to trigger them by those names, and also allowing the module user to acknowledge them in a similar way.
  - Adding `ack_named_deprecations` to module's `argument_spec` when they exist.
  - Providing doc fragment for `ack_named_deprecations`.
- Added method `__quit_module__` providing a hook for code that needs to be run when quitting the module.
- Created convenience classes combining `ModuleHelper`, `StateMixin`, `CmdMixin`.

* Improvement on Named Deprecations

Per the comments in PR, we want to expose a call to a ``deprecate`` method on the module code, so that pylint can properly perform its static analysis on deprecations.

This prompted a revamp of the named deprecation feature.

* Use .get() instead of [] for the param to ack named deprecations.

* Changes from suggestions in the PR

* removed named deprecations

* Update changelogs/fragments/1480-module-helper-improvements.yml
