Previously, whenever a KgoVerifierSequentialConsumer and a
KgoVerifierProducer ran in parallel (which a number of tests do), there
was no guarantee that the consumer would read all partitions entirely.
Whenever `wait` is called on the consumer, the `last_pass` command is
triggered without taking into account if the producer has completed.

This is problematic because it can hide stuck consumer issues. This
patch makes use of the enhanced kgo-verifier status which now contains
the high watermark for each partition. When creating a sequential
consumer, a reference to the producer can be provided. If that was the
case, when `wait` is called on the consumer we will wait until the
producer has finished and the high watermarks match.

This commit updates the SI configuration usesd for the
CloudStorageTimingStressTest(s) to upload the manifest at each
oportunity. The change should make the test more robust.
