Ensure the verify-permissions playbook executes

Add pre_tasks section to the playbook to load variables via the set-vars role.
All playbooks should do this.

Eliminate specification of owner/group in the test for cache writing by meza-ansible:

- owner: "{{ ansible_user | default(ansible_env.USER) }}"
- group: "{{ group_apache }}"
because those cause a chmod which is not allowed even though meza-ansible
can write to the cache directory.

Note: although we could get a full shell with
become_flags: '-i'
this is not necessary for testing write permissions in the cache directory

Ensure message display by filtering items to integer with the 'int' jinja filter

Final work following on b3badfc

Fixes Issue #186
