Merge branch 'erichlf/cime/config_pes' (PR #1435)

Both cime/config/acme/allactive/config_pes.xml and
cime/config/acme/allacitve/config_pes.xml.cime2 are deprecated in favor of
cime/config/acme/allactive/config_pesall.xml and so these files have been
removed.

Also remove cime/config/acme/allactive/config_compsets.xml.cime2

[BFB]

Fixes #1434

* erichlf/cime/config_pes:
  Removed config_compsets.xml.cime2
