Improve site exploitation

Increase stability with exploitation.
What's the problems now:

- No auto backups
- Containers lay down on every release
- We are not informed on accidents such as import db failure
- Write info logs to some file with good storing. Now they are writing only to the console
- Add drone badge


**Disk leaks**
- /var/lib/collectd
- /var/lib/docker: containers/, volumes/, overlay/
