ZCFLK ADD-Add a Coupling Facility to the Coupling Facility Locking Configuration

Use this command to add a coupling facility (CF) to the CF locking configuration, which then enables the CF for use as an external locking facility (XLF) so new locks can be stored on it. Lock residency is recalculated on a module-by-module basis for all modules that are currently running with CF locking to include this CF.
