Cleaning up yamllint errors.
- Use .yamllint.yml and .yamllint_defaults.yml instead of
.yamllint.yaml.
- Fix the invalid indentations.
Cleaning up ansible-lint errors.
- Add "name" to every task.
- Use command rather than shell
- Add "changed_when: false".
- Use '|' instead of '>' for the shell module.
- Fix '/bin/sh: line 3: CRYPTO_POLICY: unbound variable'.
- Add "set -eu" and "set -o pipefail" if pipefail is available.
Note: "pipefail" is not available in "sh" and "dash".
- Add "- '306' # Shells that use pipes should set the pipefail option"
to .ansible-lint since ansible-lint does not recognize it if it's set
in "if set -o | grep pipefail".
