 responses to an HTTP GET request and an XML-RPC method call.
 
 Version 2.2 of OVSAgentServer returns a distinctive string in response to an
-HTTP GET request. However version 3.0 returns a generic response that looks like
-any other BaseHTTP/SimpleXMLRPCServer. Both versions return a distinctive error
-message in response to a <code>system.listMethods</code> XML-RPC call, which
-however does not distinguish the two versions. Therefore we use this strategy:
-(1.) Send a GET request. If the version 2.2 string is returned, return "2.2".
-(2.) Send a <code>system.listMethods</code> method call. If an OVSAgentServer
-error is returned, return "3.0".
