Allow perf-simple-query to compare audit-rule matching
with the category/keyspace/table audit filters under
the same workload.
Register a hardcoded "tester" role with the audit cache
so rules targeting that role exercise the preprocessed
fast path.
The new option was used to measure audit-rules
performance against the category/keyspace/table audit
config. The results are as follows:
