ess/alps: add initial alps ess component

Note this alps ess component has nothing to do
with the old CNOS alps component used on
Cray Seastar/Portals3 (Cray XT) systems.

To work properly, changes need to be made to the
open method of the ess/pmi component to keep it
from selecting, and thus initializing, the opal/pmix/cray
component.
orte/common/alps: add an alps common lib to orte

Add an alps common lib to orte.  Add a function
to determine whether or not a process is in a
PAGG container.

Note: we need a better naming convention for
common libs, since right now they use a "flat"
naming convention.
odls/alps: make sure PMI env. variables set up

Add call to orte_odls_alps_get_rdma_creds in the
local proc launch step to obtain the Cray Rdma
credentials from the apshepherd, and to set
the PMI env. variables expected by uGNI BTL, etc.
alps configury changes

Clean up the orte_check_alps.m4.  There was a little of
unnecesary stuff for handling cle 5, since it wasn't actually
doing the right thing, which would be to use pkg-config to
find dependencies both for dynamic and static linking.

Decouple the searching for alps libs, etc. from cray pmi.

Switch the alps ess  and alps odls components' config files
to use the ALPS m4 macro.

alps configury fixes

Improve a check for detecting CLE release.
Improve an error message.
orte/mca/common: add missing Makefile.am
orte/mca/common/alps: fix configure file

Fix configure file for alps to actually check for
alps being available.

Also include stdio.h explicitly in common_alps.c
pmix/cray: remove finalize call from comp close

The finalize call in component close method is
no longer being matched by an equivalent init call,
so remove this call in the close method.
