Upgrade spectrum-mpi module on Summit

[dqwu]

On Summit, the current default spectrum-mpi module is:
spectrum-mpi/10.3.0.1-20190611

PS, "module avail spectrum-mpi" shows this version only.

If we purge this latest version and load spectrum-mpi/10.3.0.0-20190419,
"module list" marks it as a hidden module:

spectrum-mpi/10.3.0.0-20190419 (H)
  Where:
   H:  Hidden Module

This suggests that spectrum-mpi/10.3.0.0-20190419 is deprecated on Summit.
However, it is still the specified version in latest config_machines.xml:

      <modules compiler="ibm" mpilib="!mpi-serial">
	    <command name="load">spectrum-mpi/10.3.0.0-20190419</command>
      </modules>
      <modules compiler="pgi.*" mpilib="!mpi-serial">
	    <command name="load">spectrum-mpi/10.3.0.0-20190419</command>
      </modules>
      <modules compiler="gnu" mpilib="!mpi-serial">
	    <command name="load">spectrum-mpi/10.3.0.0-20190419</command>
      </modules>

If spectrum-mpi/10.3.0.0-20190419 is used, a low-res F case (e.g. --compset FC5AV1C-H01B --res ne4_ne4) fails on Summit:
SIGSEGV - Segmentation violation in procedure ncmpiio_open

Switching to spectrum-mpi/10.3.0.1-20190611 seems to work.

I've had luck by removing the version completely when running with the ECP fork. I also had to remove the versions from other libraries and that seemed to fix some issues we were having.

We explicitly mention software versions in master to record what was known to work (last known good configuration) and keep track of changes in software environment.
