Reduce number of operations in Redis benchmark.

The redis benchmark has inconsistent data due to timeouts. In general,
operations on a redis DB are pretty uniform WRT performance and having
a large set of operations is not useful for regression checks.

Add another test method with a smaller subset of operations and a filter in
the buildkite pipeline files.
