ovs-sandbox: Add an option to allow running ovs-vswitchd under gdb
It is some times useful to leverage the sandbox facility to experiment
and explore the internals of ovs-vswitchd. Since GDB requires console
access for user inputs, this patch launch an xterm for GDB, The main
terminal continue to run the sub-shell as before. Exiting the sub-shell
will also kill the ovs-vswitchd under GDB (but not GDB itself currently)
