Remove Insights support

[mykaul]

Motivation

Cherry-picked from apache/cassandra-python-driver@c948fa1 (CASSPYTHON-24). Insights was a DSE-only monitoring/telemetry feature; it has no relevance for Scylla and is being dropped upstream, so we drop it here too.

Change

• Removed cassandra/datastax/insights/ (registry, reporter, serializers, util) and MonitorReporter.
• Removed Cluster.monitor_reporting_enabled/_interval, client_id, application_name/application_version, and the corresponding __init__ kwargs.
• Removed tests/unit/advanced/test_insights.py.
• Fixed fallout in tests that passed the now-gone monitor_reporting_enabled kwarg.
• Kept all Scylla-specific fork additions (tablets, shard-awareness, client routes, ApplicationInfoBase) untouched — unrelated to Insights despite similar field names.

Tests

• Full unit test suite passes: 681 passed, 46 skipped.
• Verified pyproject.toml parses and cassandra.cluster imports cleanly after the change.

📝 Walkthrough

Walkthrough

The change removes DataStax Insights monitoring from Cluster and Session. It removes related public constructor parameters and attributes, reporter lifecycle handling, and Insights-specific logging. Hostname resolution keeps a local endpoint map for unresolved contact-point errors. The Insights registry, reporter, serializers, utilities, and tests are deleted. Setuptools no longer packages the Insights module. Existing test setups no longer pass the removed monitoring option.

Merge Risk:🔵 Low · up to b167c

The change leaves RetryPolicy() in a function default argument, violating the repository’s linting rule; changing the default to None and initializing it inside init is needed before merge. This is a localized, low-impact follow-up.

Remove the function call from the default value.

Ruff reports B008 for retry_policy=RetryPolicy(). Use None as the default and create RetryPolicy() inside __init__.
