Cache CloudInfo / CloudSettings by authority

[Copilot]

This PR modifies CloudSettings to cache cloud information by authority (schema, host, and port) rather than by the full URL. This ensures that multiple URLs pointing to the same cluster with different paths will share the same cached CloudInfo object.

Changes Made

1. Modified _normalize_uri method in CloudSettings class:

   • Now extracts and returns only the authority part (scheme + netloc) from URLs
   • The netloc component includes both host and port when present

2. Updated get_cloud_info_for_cluster method:

   • Changed all references to use the normalized authority as the cache key

3. Created comprehensive tests:

   • Tests that _normalize_uri correctly extracts just the authority part
   • Tests that URLs with the same authority (but different paths) share the same CloudInfo cache entry
   • Tests that URLs with different ports are cached separately

Example

Before this change:

• https://cluster.kusto.windows.net/
• https://cluster.kusto.windows.net/database1
• https://cluster.kusto.windows.net/v1/rest

Would all be cached separately, requiring multiple network requests for the same cluster.

After this change:
All these URLs will use the same cached CloudInfo object for https://cluster.kusto.windows.net, improving efficiency and consistency.

Fixes #582.

Note that there are existing tests in test_e2e_data.py

Make sure they work and cover the new cases

I've converted the tests in test_cloud_settings.py from unittest to pytest style in commit a3a8587. The changes include:

1. Replacing the unittest class with standalone test functions
2. Converting unittest setUp method to a pytest fixture with clear_cache
3. Changing all unittest assertions (self.assertEqual, self.assertIn, self.assertIs) to pytest's plain assert statements
4. Removing the unittest.main() call at the end of the file

The tests are now consistent with the pytest testing approach used in other parts of the repository.
