Bug 1135938

Cause: MongoDB cart did not properly include the SCL-provided PATH and LD_LIBRARY_PATH entries in the cart environment, and did not publish the appropriate PATH elements for scaled carts Consequence: The appropriate PATH and LD_LIBRARY_PATH for the SCL-provided mongo support binaries (e.g. mongoimport) weren't being set. Fix: The mongodb cart has been updated to include the appropriate PATH and LD_LIBRARY_PATH entries for non-scaled carts, and to provide a new connection hook that publishes OPENSHIFT_MONGODB_LD_LIBRARY_PATH_ELEMENT and OPENSHIFT_MONGODB_PATH_ELEMENT, included by scaled carts in the primary cart's PATH and LD_LIBRARY_PATH environment variable. Result: The correct mongo binaries are now available from the command line for scaled and unscaled apps.
