The problem lies in this patch:

https://review.openstack.org/#/c/96300

Even If I apply it, i get an error that Unknown Neutron context. The patch
is correctly applied - some 20 times :)

Task and output is as follows:


{

    "VMTasks.boot_runcommand_delete": [

        {

            "args": {

                "flavor": {
