Ansible style fixes based on the Ansible linter output

[duelle]

Only to be merged if you deem it helpful/meaningful.

This should resolve about 700 warnings from the Ansible linter. Some are remaining, mostly including lines that are too long and wrong indentation.

What was mostly resolved:

• comment space fixes
• removal of trailing spaces,
• yes -> true,
• no -> false
• Wrongly written true/false
