We were told today that OpenMPI 3.1.0 does not really work for this build on 'waterman' (and perhpas other Power8 and Power9 machines). They must just remove the env altogether.

Description
Switches from OpenMPI 3.1.0 to OpenMPI 2.1.2 env on Power9 'waterman'. We were told by @nmhamster today that OpenMPI 3.1 really does not work on the Power9 (and is a known issue apparently) and to use the OpenMPI 2.1.2 env instead.
Motivation and Context
This appears to fix a bunch of failing tests including those in #3344, #3331 and perhaps others.
How Has This Been Tested?
On 'white' I ran:
and it returned:
This is worth trying on the full ATDM Trilinos build.
