Package installs should use the state `present` so running the playbook for the
second time would not change the package version. To achive repeatability
between several deployments playbook should specify the particular version of
the package (not implemented).
Ansible-lint rule reference:
[ANSIBLE0010] Package installs should not use latest
Ansible lint throughs warnings about swap tasks using the shell module. Based on
my experience the way these tasks are implemented is the optimal one. So I
decided to mute the warning and keep using shell module.
