Prior to this commit, the hostname was set with one big bash script and attempted to determine what tools are available. This commit changes that by splitting out that tool check on the Vagrant side of things with the GuestInspection class, and adds back restarting networking to get a DHCP lease with the change rather than using `dhclient`. This pattern matches how hostnames are set in the redhat capability.
