Merging per testing team conversation meeting.
* Correctly check for default packagesets for each flavor
* FIF updates for default packagesets
- Set DESKTOP=gnome to trigger graphical_wait_login instead of
console_wait_login
- Increase virtual disk size to account for default packagesets
* Correctly check for minimal-iso default packageset
* Updated needles for issue 16
* Update templates.fif.json with package set test suites
Package sets tested per ISO will follow these conventions:
- Test suites will not be duplicated between the boot and dvd ISOs
- All default package sets will be tested against dvd-iso
- Boot ISO will be considered valid if `minimal` package set installs
cleanly
* Do not add updated needle with changed hostname
