given the cyborg api has 2 enpoint with like 10 effective action you can prefrom
crun operation on acclerator + deployable + program
it shoudl be trivail to add port to an osc pugin at this point.
if you add the api suport to the openstack sdk frist you can kill two brid
with one stone and just make the osc plugin for cyborg call the sdk function
then compltel drop python-cyborgclient
cfom a nova integration point of view we could then also jsut use the sdk functions.
