Restart CLVMD with same cluster manager Add named cluster_ops to easily learn the name of the active cluster manager, so we are able to restart singlenode manager in testing. Add simple test for clvmd -S (restart) and -R (refresh) (though it needs some extensions).

Use execvp for clvmd restart Since execve passed only NULL as environ, we had lost all environment vars on restart - thus actually running 'different' clvmd then the one at start. Preserving environ allows to restart clvmd with the same settings (i.e. LD_LIBRARY_PATH) Add test for second restart.
