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
