Add post delay to reboot

Leapp may reconfigure network after main upgrade. Also systemd may bring
down and up again network unit. This patch adds post_reboot_delay as 2 min to
mitigate such issues which can be configurable as heat variable in
customers env files for some very specific cases. Also test_command is
changed from whoami to systemctl to have better assesment when a system
completed its boot.
