Test vovserver socket connectivity.

The command vovtestsocket attempts to connect to the specified port on a host. It must be called from a vov-project enabled shell. It prints the result and also places it in a property on the trace (object 1) in vovserver.
Important: The vovserver for the project must be running.

The result is printed and a time-stamped property of the form SOCKET_<HOST>_<PORT> is attached. See example below.
