New model manageiq manageiq user (#26641)

* ManageIQ: manageiq_user module, module utils and doc_fragment

ManageIQ is an open source management platform for Hybrid IT.

This change is adding:
- manageiq_user module, responsible for user management in ManageIQ
- manageiq utils
- manageiq doc_fragment

* Handle import error

* Use formatting options

* group parameter is required

* changed doesn't need to be an attribute

* resource dictionary should contain values which isn't None

* move from monitoring to remote-management

* Use ManageIQ nameing convention

* Do not set defauts in arguments

* Use idempotent state parameter instead of action

* Check import error in the manageiq util class

* Update the miq documentation

* rename the connection configuration from miq to manageiq_connection

* All messeges start with non cap, fix typos, add examples, rename vars

* more typos fixes

* Make sure we insert only strings to logs by using % formating

* use suboptions keyword for the manageiq connection

* do not log the managiq connection struct (it include sensitive information like username and password)

* add missing from __future__

* ahh, wrong no-log line

* Use sub options
