bq.
dtest-latest.client_request_metrics_test.TestClientRequestMetrics.test_client_request_metrics
This test shouldn't be applied. With Paxos v2's reads, contention is much less
likely to occur because v2 can use optimistic reads that don't require a full
Paxos (3-4) round unless there's in-progress state.
The test is running 20 concurrent SERIAL reads on the same partition (k=0),
trying to generate contention. That doesn't happen with v2.

dtest-latest.client_request_metrics_test.TestClientRequestMetrics.test_client_request_metrics
This test shouldn't be applied. With Paxos v2's optimistic reads, contention
is much less likely to occur because v2 can complete reads in 1-2 round trips
instead of 3-4 and uses optimistic reads that don't require a full Paxos round
unless there's in-progress state.
The test is running 20 concurrent SERIAL reads on the same partition (k=0),
trying to generate contention. That doesn't happen with v2.
