v02.a

[v0.2a] - 2021-05-18

NEW

• Made ACME PEP 517 compliant: added pyproject.toml and modified setup.py
  accordingly
• Added IBM POWER testing pipeline (via dedicated GitLab Runner)

CHANGED

• New default SLURM partition set to "8GBXS" in esi_cluster_setup

REMOVED

• Retired tox in slurmtest CI pipeline in favor of a "simple" pytest testing
  session due to file-locking problems of tox environments on NFS mounts

FIXED

• Stream-lined GitLab Runner setup: use cluster-wide conda instead of local
  installations (that differ slightly across runners) and leverage tox-conda
  to fetch pre-built dependencies
• Opt-in pickling was not propagated correctly in daemon-reentry situations
