ansible2.0以降の「yum:」「apt:」で「name="{{ list }}"」が指定できるようになった。
with_itemsでループさせない。
[DEPRECATION WARNING]: Invoking "yum" only once while using a loop via squash_actions is deprecated. Instead of using a loop to supply multiple
items and specifying `name: {{ item }}`, please use `name: [u'firewalld']` and remove the loop. This feature will be removed in version 2.11.
Deprecation warnings can be disabled by setting deprecation_warnings=False in ansible.cfg.
