dnfdaemon: Make it possible to set 'interactive' option for Goal::do_transaction()

The operation can require root privileges, for which it can ask the user
through polkit. It's okay when the operation is interactive, aka issued
by a user, but when the operation is ran by a background service, then
the password prompt coming out of blue is wrong. This change allows to
tell the daemon server whether it can ask for the root password or not.
