Refactor helpers to return unicode strings
Make sure that CLI always deals with unicode.

To make it simpler and safer to use strings via CLI, all data that gets
passed to Paramiko gets encoded to UTF-8 and all data returned from
Paramiko gets decoded to unicode.
Added some more tests for products
Removed print statements.
