Subject: [PATCH] Print logs in case of error

Print system logs (e.g. systemd), Riak errors, Solr logs, Ansible logs.

Prefer making Ansible to log to local file instead of [default
syslog](https://docs.ansible.com/ansible/intro_configuration.html#log-path)
in order not to spam syslog and to ensure printing out of all Ansible
logs (e.g. for identifying a "changed" task in the middle while
testing Ansible idempotency).
