mca_base_param_files option is no longer read and should be removed

[wckzhang]

ompi_info and the code show an mca parameter as:

MCA mca base: parameter "mca_base_param_files" (current value: "/home/ec2-user/.openmpi/mca-params.conf,/home/ec2-user/ompimaininstall/etc/openmpi-mca-params.conf", data source: default, level: 2 user/detail, type: string, synonyms: mca_param_files)

However, when I actually provide this parameter, it doesn't seem to be getting picked up.

Thanks ! I was just struggling with the same issue. The reason is still eludes me.

We should probably remove the code and have it not show up in ompi_info considering it's not being used from mpirun

We decided during the weekly telecon that our course of action here is to have a hard abort if the user attempts to use this parameter.

Created an issue in PRRTE - openpmix/prrte#1731
There's a conflict with how we prefix different projects and needs more community feedback.

@jsquyres @rhc54 Can we assign this issue to another person as William is no longer working on ompi?

[jsquyres]

Sure, who do you want me to assign it to?
