Show a warning when PXE template is edited
Show a warning when PXE template is edited and the template has some associated hosts in build mode. The warning box should read something like:
The template has hosts in build mode associated, to apply the change trigger building mode again.
I was testing RHEL7 provisioning for two days not realizing the fact that PXE templates needs to be re-rendered. I was rebooting over and over again with the same (incorrect) kernel options :-)
