As a library feature, percentile is better to be configurable.

What does this value 64 imply? Does it need to be configurable for different latency anomaly use cases?

The -slim-bookworm here replaced with -bookworm. However, the same -slim-bookworm at line 31 remains unchanged. Why is the difference?
Explain what this PR does.
This PR supports Anomaly Detection on fields that use valuesDoubleSketches. We add aggregations and postaggregations which run natively on druid. These sketches are converted to values using these postaggregations and are run on druid.
This would enable us to use anomaly detection for inputs using sketches(https://datasketches.apache.org/). For example, latency based anomaly.
Also, I have made few changes to DockerFile and added a patch for Numalogic 0.9.1 to avoid CVE issues. This is important for the perf-anomaly team to avoid moving to Numaflow 1.2.1 and updating all the UDFs and UDSinks. This would help them save lot of time by just upgrading the ML vertices.
