It will be nice to have possibility to kill VM immediately after build finish. It will allow us to make sure only one build is executed on clean-well defined VM. Sometimes builds change the state of the vm(they shouldn't - but sometimes happen from many reasons) and it will be nice to have way to enforce new VM each time.
Right now when some build wait in the queue for executor, after finish some other job related with that label new build will be spawned on the same machine(VM) that previous one finish.
Right now we have field: "Node Retention Time" but looking at the description setting this as "0" doesn't sounds like good idea.
It will be nice to have for example checkbox.
