Basically, we are now installing a small wrapper in /usr/local/bin
which just echoes to stdout what should be in the authorized_keys
file for that user.
That content is generated by retrieving the ssh key from sssd via
the command sss_ssh_authorizedkeys as well as the usual ssh way to
restrict the action an user/key can do: command="...".
In this case, we're setting a couple of environment variable that
are needed later on for things to work properly as well as only
allow the user to call the aclchecker.py script provided by pagure.
