Add os_stack module for create, update and delete stack (#2002)

* Add os_stack module for create and delete stack

* Add ansible module for creating and deleting heat stack
* Parameters:
  - stack name
  - template
  - environment_files (list)
  - parameters (dict)
  - timeout
  - rollback
  - state: In a near futur I would like to improve
    this module by providing a way updating the stack
    if already exist. Shade doesn't offer this functionality
    AFAIK

* Add update stack feature

* Update added_version and return doc

* Add copyright for os_stack module

* Add wait user choice and minor fixes

* Remove Todo for Shade 1.8.0 and bad line example

* Add documentation for the return values

* Fix type on return value

* Fix yaml syntax

* Cast message to string instead

* add missing check mode
