In some cases ovsdb server or relay gets restarted, ovsdb python clients
may keep the local socket open. Instead of reconnecting a lot of failures
will be logged.
This can be reproduced with ssl connections to the server/relay and
restarting it, so it has the same IP after restart.
This patch catches the Exceptions at do_handshake to recreate the
connection on the client side.
