WORKAROUND singularity

Currently ohpc-base-compute package won't install as it declares it requires a singularity package which doesn't exist. A hacky workaround is to run the below, but this needs to be AFTER slurm.yml has failed once, as that installs the necessary OHPC repos. A proper fix is pending ...

- hosts: compute
  become: yes
  gather_facts: no

    - name: Install dependencies for ohpc-base-compute
