Use package module to install distro packages

Consolidate distro package install tasks into a
single task using the package module.

The minimum Ansible version is raised to 2.2 due to a
known bug [1] in Ansible's apt module which does not
update the cache properly if the cache update and the
install are combined in a single task.
