LP#1657885: Inform Vandelay of new chunking/bundling logic

There is a naive attempt to force immediate streaming of results in Vandelay
for certain processes, but it both only helps a little, and breaks under the
new OpenSRF bundling/chunking logic.  So, we'll drop it where it's not
directly configurable, and test for the appropriate features where we can.
