Feature: improve checkmode outputs

[BobVanB]

Checkmode has workable and readable output in console.

This code adds mainly these features:

• some labels to the output to make it readable.
• Faster async with checkmode
• Checkmode wil fail at the end of the dispatch, to make it faster to fix multiple issues and not 1 by 1.
• workflow_launch.name is mandatory: workflow_launch_module.html#parameter-name

This is visible with a basic playbook command.

ansible-playbook --check ...

Is there a relevant Issue open for this?

Not Available
