[examples] add replication demo

Adds a self-contained Docker Compose environment demonstrating
Kudu-to-Kudu replication with Apache Flink.

The setup includes two Kudu clusters (source + sink), a Flink cluster,
a Python ingest simulator, and a Prometheus + Grafana observability
stack with a pre-built replication dashboard — all wired together and
ready to run.

A Makefile covers the full workflow: building the replication JAR,
starting and stopping the stack, submitting and savepointing the Flink
job, and verifying row counts across clusters. Version pins and tunables
are centralized in .env.
