Cluster test daint

Part of #202 and !168 (merged)

• double ssh access

  $ ssh USER@ela.cscs.ch
  [USER@elaN ~]$ ssh daint

• daint mock CI job
• modules:
  • python/3.6.0 python/3.7.1 (up'ed only because of zlib install issues) => cray-python/3.6.5.7
  • r/3.4.0 => cray-R/3.4.2
  • open_mpi/3.0.0 => cray-mpich/7.7.10
    • does not load neither mpich nor mpirun binary? (PrgEnv-intel/6.0.5 cray-mpich-abi/7.7.10 does)
• local paths (scratch)
• move from LSF (bsub -K) to Slurm (srun/sbatch --wait)
  • test dropping --connector legacy
