GitLab

- doesn't work right yet for margo tests

- just does software build right now, does not include job script

- consistent with theta emails now for mail filter consistency

- gets ofi pingpong test running correctly again
- also commentted out some extra diagnostic runs for now

- use fork of mercury
- set run time option to prevent it from blocking (or initializing cci
  in a way that allows blocking)
- re-enable HG_Finalize calls in tests

this functionality requires a c99 compiler, which may not be
available on all systems

suggested by Howard Pritchard to avoid potential conflicts with mpich

still not functional on cooley

current master version of mercury should automatically enable SSE4
checksumming, which is not expected to impact performance

- cooley cci config file now included in the repo
- CCI_CONFIG and LD_LIBRARY_PATH env vars set in one script only
- bumped up max walltime to 10 minutes
