investigate hbp job runner

[k-dominik]

our collaborators have implemented a first version of the UNICORE job proxy. Current features seem to be

• Job submission to unicore
• database with costs per job for each ebrains user

in the future they want to add

• quota management.

There is a jupyter notebook demonstrating how to run jobs with their service. We should investigate this, see how suitable it is for our needs and collect feedback in order to drive further development.
