Add "pml_ucx_tls" parameter to control the transports to include or exclude (with a '^' prefix). UCX will be enabled only if one of the included transports is present, or if a non-excluded transport is present (in case of exclude-list with a '^' prefix). Add "pml_ucx_devices" parameter to control the devices which make UCX component set a high priority for itself. If none of the listed devices is present, the priority will be set to 19 - lower than ob1 priority. Signed-off-by: Yossi Itigin <[email protected]> (cherry picked from commit 562c57c)
