This patch resolves a minor issue that was generating a "warning"
message when running the galera-install.yml playbook.
The "{{" and "}}" are not required for conditionals, and loop
expressions, so these can and should safely be removed from "when:"
statements and "with_items:" statements.
Functionality does not change but the warning message will go away after
this patch.
