Update role so we're not reloading the daemon in excess

The systemd-networkd role was reloading the systemd daemon on every run
this change removes that as this role will not need to modify anything
that requires a daemon reload.

Network facts will be gathered after this role executes which will
ensure any state changes are picked up as soon as they're available.
