What

For Confluent Platform.

These configs rely on a jar file that ships with Control Center, so we need to remove these configs when running with 8.0 (but keep them when running in 7.9 or lower).

Since we're using ZK for 7.9 or lower and KRaft for 8.0 and above, this PR implements this change by only setting these configs when running in ZK mode.

Blast Radius

This change is applied to the following local services: connect, kafka rest, ksql, and schema registry.

Blast radius should be minimal since these configuration options are optional.

Pull Request Overview

This PR adjusts the behavior of the CLI so that the monitoring interceptor configuration options are only set for services running on Confluent Platform 7.9 or lower (i.e. in Zookeeper mode).

• Adds an extra condition to ensure interceptor configs are only applied in Zookeeper mode.
• Updates the conditional in getConfig for services such as connect, kafka-rest, ksql-server, and schema-registry.

Comments suppressed due to low confidence (1)

internal/local/command_services.go:470

• [nitpick] Consider extracting the overall condition into a well-named boolean variable (e.g. shouldSetInterceptors) to improve readability.
