[BEAM-2439] Dynamic sizing of Datastore write RPCs
This stops the Datastore connector from always sending 500 entities per RPC.
Instead, it starts at a lower number which is more likely to complete within
the deadline even in adverse conditions, and then increases or reduces the
batch size in response to measured latency of past requests.
