Allow specifying remote user (and key?) for provision.sh

[mikaelkundert]

In our ansible configuration we have user specified as root and we would like to keep it that way. But we would need an option to specify the remote user and/or key for remote server as our team has their own personal sudo accounts to the server.

Ideal usage example:

$ ./provision.sh -fm dbrootpasswd -p file.txt -u myuser production
