PSM2 MTL uses same help filename as PSM MTL

[jsquyres]

Both components have a help-mtl-psm.txt.

The PSM2 MTL should rename its helpfile to be help-mtl-psm2.txt.

@matcabral Can you fix?

Additionally, the help message checker turned up this (which may be just another symptom of the duplicate filename):

*** WARNING: Possibly unused help topic
  Help file: ./mca/mtl/psm2/help-mtl-psm.txt
  Help topic: debug level
*** WARNING: Possibly unused help topic
  Help file: ./mca/mtl/psm2/help-mtl-psm.txt
  Help topic: path query mechanism unknown

Hi Jeff,

Intel PSM team renamed all the externally exposed symbols in psm2.so to address the issue discussed here: http://www.open-mpi.org/community/lists/devel/2015/09/17919.php . To support that change I updated Open MPI PSM2 MTL, including the change you suggest above. I’m in the process of testing the changes before submitting the PR. However, I found things failing. Once I clear the findings I’ll post it.

Thanks,

[jsquyres]

Sounds good. Thanks!

@matcabral BTW, pro tip: if you include "Fixes #1018" in the commit message where you fix this help file issue, it'll automatically close this issue when your PR with that commit is merged to master. See https://github.com/open-mpi/ompi/wiki/GithubCommitMessages for a little more detail.
