[petruki]

This pull request introduces a snapshot auto-update mechanism to the Switcher client, enabling periodic background updates of snapshots. It also refines context and authentication initialization, and improves the test suite to cover the new functionality. The most important changes are grouped below:

Snapshot Auto-Update Feature:

• Added the SnapshotAutoUpdater class to handle periodic snapshot updates in a background thread, with methods to schedule and terminate updates. (switcher_client/lib/snapshot_auto_updater.py)
• Updated the Client class to use SnapshotAutoUpdater for scheduling and terminating snapshot auto-updates, removing the previous check logic. (switcher_client/client.py) [1] [2] [3]

Context and Authentication Improvements:

• Refactored ContextOptions and Context constructors to use type annotations and improved parameter handling. (switcher_client/lib/globals/global_context.py)
• Simplified GlobalAuth.init and RemoteAuth.init to remove the unused url parameter. (switcher_client/lib/globals/global_auth.py, switcher_client/lib/remote_auth.py) [1] [2]
