OpenMPI with --with-verbs and --with-ucx support for HPC

[rahulunair]

Looking at the spec[1] for Clear's OpenMPI bundle, it seems that it does not seem to have support for openfabrics and ucx which is an important aspect of using OpenMPI on HPC, could we please enable these as part of the official bundle:

The flags that are required to enable these are:

--with-verbs --with-ucx

ucx is a dependency and can be sourced from the github link: https://github.com/openucx/ucx
