Multiple executables

[Zarquan]

Thinking about the use case described by colleagues from Australian SRC node.
If we have multiple executables, we can assign them to compute nodes using references.
In theory, a many to many relationship.

• Simple use case
  • One executable on one compute node
• Remote desktop with several applications installed
  • Several executables on the same compute node
• Distributed executable e.g. Dask or a pipeline
  • The same executable on several compute nodes

Not for this iteration, but keep it in mind for the future.
This isn't that complex to implement if we have access to a VM based cloud compute platform e.g. Openstack, DigitalOcean, Amazon etc ..
