yamllint: make files compliant

To aid pre-checks before submission, lets make the files pass
the default yamllint checks - then we can use yamllint to check
new changes going forwards.

Changes were:
 - change True to true for some bools (which also then matches
   the zuul gerrit driver docs)
 - add '---' document start lines
 - wrap one >80 char line using a '>' string construct
