KIP-1147 — Improve consistency of command-line arguments

Accepted Kafka 4.2 Admin

Adds --bootstrap-server to kafka-producer-perf-test.sh, introduces --command-property as a consistent replacement for --producer-props, and adds --command-property to kafka-consumer-perf-test.sh and kafka-share-consumer-perf-test.sh. Different perf tools used different argument names for the same concepts (e.g., bootstrap.servers vs --bootstrap-server), creating unnecessary friction and inconsistency for operators running comparative benchmarks.
