VM decommissioning

[mbdebian]

Please, have a look at the be-debian-worker-mk VM which was shutdown long time ago and I don't think is of any use, to find out whether we could decommission it.

VM: be-debian-worker-mk Project: open-targets-platform

[mbdebian]

We'll create a disk image for the machine with a description that contains the information related to machine geometry, and then destroy the machine itself

Created an image, which contains everything required to recreate the VM. But just in case, here is the CLI for creating a similar VM.
