Implementation of the ProxyPullConsumer interface.
Tries to get messages by using pull() then try_pull() method calls, but prefers pull(). Switches between pull() & try_pull() if it gets an exception. Only gives up when both methods have returned two consecutive exceptions.
Note, our own implementation of ProxyPullSupplier::pull() is very basic.
