Make ansible-lint and yamllint use more strict rules.

This patch modifies configuration of both ansible-lint and yamllint
to check for more rules, resulting in a more strict verification.

For ansible-lint verification of errors 301, 305 and 505 are skipped,
due to false positives. For the same reason, 'experimental' rules
are skipped.

ansible-lint error 306 is skipped since the fix is to set pipefail,
which is not available in all shells (for example dash, which runs
ansible-freeipa CI).

Yamllint disabled rules (comments, and indentation) would introduce a
huge amount of small changes, and are left for future changes, it
deemed necessary.
