REST client GET session timedout bump
REST client GET session timedout bump

REST request seems to have delayed more than default 10 seconds
forcing the client code to close the socket leading to server
throwing "AssertionError". The default for GET is increased from
10 seconds to 30 seonds to minimize impact on the test client.
