Update capability to use guest inspection module for determining
correct actions to execute. When systemd is in use restart the
correct active service, either NetworkManager or networkd. Default
to using the original service restart when systemd service is not
found.
`/etc/init.d/network restart` already restart NM and shutdown interfaces.
In start() :
```
if [ "$(LANG=C nmcli -t --fields running general status 2>/dev/null)" = "running" ]; then

This reverts commit 166d10d4e16836e908be0bd94c2f671cac2b38b4.
RHEL-7 / Current Fedora versions tend to use NetworkManager for
configuring the networks, and `service network restart` might fail.
If the `NetworkManager` service is running, we should restart it,
otherwise we try restarting `network`.
the previous fix for #4465 assumed that the NetworkManager takes care of updating /etc/hosts with
the new hostname, but testing shows it doesn't. This change ensures that the change is always added
to /etc/hosts when the name changes.
This PR sets the active hostname back to the name specified in the Vagrantfile (fqdn) and updates the unit tests.
Setting it to the short name causes loads of problems while configuring the system. I've had issues with sudoers hostname matching, Weblogic certificate generation and a few others. Even if I changed all of the Chef recipes, the fqdn is set in /etc/sysconfig/network so the active hostname will switch to the fqdn after a reboot.
