imo we should unify somehow these parameters. some are passed as a script param (ex. IP address), some are taken from env variables. Maybe we could use sth similar to this: http://stackoverflow.com/a/10551190/761782 - then we could specify variable either by env variable or by script param?

[xor-xor]

That's intentional :) You most certainly do not want to pass any sensible data (e.g. credentials) via script params. But I see your point, and I think that moving IP address argument to env var would be a good move here (these scripts are not meant to be launched directly by user anyway...).

[xor-xor]

Done (credentials and IP address are taken only from env vars).

@mkurek + @quamilek - my last activity in this PR (i.e., after you both accepted it) looks like two commits have been added, but it's just a resolution of merge conflict by making two cherry picks - nothing has changed.
