🚨 ansible-lint code quality improvements.

[bbaassssiiee]

152 reported the output of ansible-lint of a playbook with all these roles. There was clearly room for improvement, and I did some power-editing to refactor all the simple code-style issues. Each commit in this PR addresses one type of issue reported by ansible-lint, on all the roles.

After merging this, there is still work to do by the regular maintainers to bring this repo up to the ansible-galaxy standards. A few long lines could still be simplified. And then please address the remaining issues in several places:

• [x] [201] Trailing whitespace.
• [ ] [204] Lines should be no longer than 160 chars.
• [x] [206] Variables should have spaces before and after: {{ var }}.
• [x] [305] Use shell only when shell functionality is required.
• [x] [502] All tasks should be named.
• [x] [701] Role info should contain platforms.
• [x] [702] Galaxy tags must contain lowercase letters and digits.
• [x] [703] Should change default metadata.
• [x] [301] Commands should not change things if nothing needs doing.
• [ ] [303] curl used in place of get_url or uri module.
• [x] [306] Shells that use pipes should set the pipefail option.
• [ ] [503] Tasks that run when changed should likely be handlers.
• [x] [601] Don't compare to literal True/False.

The volume of changes means this is going to take some time to merge. Please be patient.
