Increase timeout waiting for subscription message

Fixes #1775

Connext takes significantly longer for discovery to happened compared to the other RMWs, and so the previous 2 seconds of waiting was not enough.
Local observation shows it takes about 3 seconds to get a message from the subscription. This change bumps the timeout to 10 seconds to be conservative.
