az monitor app-insights query

Summary

Pre-announce the breaking default-value change planned for application-insights extension version 3.0.0b1.

Today, --offset defaults to 1h. The follow-up implementation will remove that implicit default so that, when no CLI time arguments are supplied, the KQL query controls the time range. Customers who require the current behavior can continue to specify --offset 1h explicitly.

This notification-only PR:

• registers the --offset default change from 1h to not set, targeting 3.0.0b1;
• links the warning to [Application Insights] Remove implicit one-hour offset from app-insights query #10363 for context and migration guidance;
• loads the notification when the extension is loaded;
• publishes the notification as preview version 2.0.0b2; and
• does not change command behavior.

Follow-up implementation: #10364. It should merge and release only after this notification has been released for at least 30 days.

Validation

• Built the application_insights-2.0.0b2 wheel and verified its package metadata.
• Installed the wheel in an isolated Azure CLI extension directory and executed the command successfully.
• Confirmed the runtime warning states that --offset will change from 1h to not set in 3.0.0b1 and links to [Application Insights] Remove implicit one-hour offset from app-insights query #10363.
• Ran azdev generate-breaking-change-report application-insights --target-version None --source pre_announce; the report collected the expected warning under monitor app-insights query.
• azdev style application-insights passes.
• python scripts/ci/test_index.py -q passes.
• git diff --check and Python compilation pass.

General Guidelines

• Have you run azdev style application-insights locally?
• Have you run python scripts/ci/test_index.py -q locally?
• My extension version conforms to the extension version schema.

About Extension Publish

This PR updates setup.py and HISTORY.rst and does not modify src/index.json. The normal post-merge publishing automation should create the index update.

The release metadata guidance is addressed: HISTORY.rst documents the customer-visible pre-announcement, and setup.py advances the notification release from 2.0.0b1 to 2.0.0b2. The follow-up breaking implementation remains separately versioned as 3.0.0b1 in #10364.
