pmm-agent should be able to send trimmed queries, examples, and fingerprints. pmm-managed should not lose that flag. qan-api2 should accept and store that flag.
We have it in collector.proto: https://github.com/percona/pmm/blob/559f6ba1560b492cc6d06f73dc75013208378ca6/api/qanpb/collector.proto#L111-L112 But there is no equivalent in pmm-agent protocol: https://github.com/percona/pmm/blob/PMM-2.0/api/agentpb/collector.proto
Actually trimming queries/examples/fingerprints should be done in PMM-5283.
