Add ability to select transport, and only compare the first one in the conduit list for a match. This lets you select which conduit to use for OFI - if you set "-mca rml_ofi_transports ethernet" you'll pickup the mgmt conduit. If you set "-mca rml_ofi_transports fabric", you'll get the coll conduit
