Unit test for query posting

[sachalevy]

Clients running queries use utils functions that wrap up around sending HTTP streaming requests to the server and iterate over the received data. We need to include some tests for different events:

• server stall (testing for time out implementation on the client-side)
• erroneous response (from server)
• unknown response (detected at client)
• successfully retrieved result
