Arvados

I need a command/API to spin up a test node in the node-manager that I can set up some parameters like:

for Azure

node-manager-ctl create_node --size Standard_D3
node-manager-ctl create_node --size Standard_D3 --image https://curoversesu92l.blob.core.windows.net/system/Microsoft.Compute/Images/vhds/su92l-compute-osDisk.e91c090d-3237-4d0f-8ab3-f92031e648c8.vhd

We could use tag_arvados-class to differentiate from normal compute nodes so it doesn't get killed right away.

also I'd like to destroy nodes like this:

node-manager-ctl destroy_node compute0

so it's cloud independent.
