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):

'https://localhost:8001/plugins/kimchi/templates' \
-X POST -d '{"name": "test-netboot", "source_media":

New subject: [PATCH] [Kimchi 1/3] Add support to create netboot templates.
From: Paulo Vital <pvital(a)linux.vnet.ibm.com>
Changed API.json and model to accept 'netboot' as source media parameter while
creating a new template.
Now, when creating a new template and specifying 'netboot' as source media
parameter, it is assumed the template will use netboot process -
PXE/DHCP/TFTP/(NFS/HTTP/FTP).
This is part of solution to Issue #372.
