Conver node_leave_cluster rpc to new style result

This patch converts this rpc call to the new style result, and also
changes in the process the meaning of the QuitGanetiException's
arguments and the node daemon rpc call exception handler.

The problem with the exception handler is that we used a two-stage one,...
