V3:
* set network as third default option to boot order
V2:
* Adapted patch to new template API (automatic detection of cdrom)
V1:
This patchset adds support in backend to create templates and guests to netboot
without setting a cdrom path or URL as image to install. Once created a guest
to boot via network, the guest will request DHCP/TFTP/(NFS/HTTP/FTP) network
installation servers to download the configured images and start the install.

To test, use the curl commands (look the parameters used):
$ curl -k -u test -H "Content-Type: application/json" -H \
"Accept: application/json"
'https://localhost:8001/plugins/kimchi/templates' \
-X POST -d '{"name": "test-netboot", "source_media":
"netboot"}'
Enter host password for user 'test':
