Address Github issue #11532 by translating legacy parameters for direct launches

[qkoziol]

Borrow code from the OMPI schizo module in PRRTE that translates legacy MCA parameters when an application is direct launched (PRRTE will translate legacy parameters when natively launched).

(cherry picked from commit 5d236e9)

Also, for my future reference and possibly other devs' knowledge: when you are cherry-picking commit(s) from the OMPI main branch to a release branch, it's better to checkout the OMPI repo without the submodules (git clone ...), then immediately check out the release branch (git checkout <branch>) and update the submodules (with "git submodule update --init --recursive") and then cherry-pick the commit(s) to the branch (git cherry-pick -x -s <hash>) .

@qkoziol the problem with the original PR was not that you did anything wrong with the cherry-pick or the PR, it was because v5.0.0 did not have a submodule update merged in that this commit depends on. Had you included the submodule update in your pr, it would have been fine (and the last pr would have also been fine if you didn't try to rebase..not sure what happened there).

As it is now, we merged the submodule update, and things are happy.

Either way it works and it is fine - thanks for bringing these back.
