I created a small hack, my ruby skills are way off, it's the first time i
code anything in ruby :)
It looks like the reboot calls goes to the smart_proxy_discovery_image
plugin which is installed in the discovery image.
I created a hack that allows me to set a kernel command line "bootpxe=1"
(any value though should work) and it will set the bootdev to pxe before
the reboot.
In the image itself, i had to add the ipmitool to the sudoers file (so my
hack will work, i also enabled the ipmitool service, didn't test without it
though).

I do still think the best option (when i'll have some spare time to dig
into ruby more) will be to set either through settings or through the
"provision" button the option to reboot but to set bootdev to pxe before
(it could be passed a param when calling the /reboot on the smart-proxy).
