ansible_mitogen: Templated SSH private key file

[moreati]

refs #1083

[moreati]

Another case of vanilla Ansible not templating ssh_executable (see #1175). It exhibits slightly differently depending on whether there is an existing connection and/or whether an SSH password is specified (requiring sshpass). It looks like private_key_file option is among those that are correctly templated.
