Remove unused DataStax Insights monitoring

[dkropachev]

Closes #1027. Part of #1025.

What and why

Remove the DataStax Insights client, lifecycle listener, schemas, monitoring option, tests, fixtures, and generated dependency-report files. ScyllaDB does not use or test Insights, so this removes background production behavior and test/build code that the team otherwise has to support without coverage.

Client/application STARTUP metadata and Scylla driver-config reporting are preserved because they have non-Insights consumers.

Validation

• mvn -pl core,query-builder,mapper-runtime,mapper-processor clean test — 4,571 tests, no failures or errors.
• mvn -pl integration-tests -am -DskipTests test-compile

Dependencies: none. Cherry-picked commits: none.
