feat: added auto refresh token #388 (#389)

[petruki]

This pull request introduces a new feature for automatic authentication token refresh in the Switcher client, along with supporting infrastructure and minor code improvements. The main focus is on enabling the client to automatically refresh its API token before expiration, improving reliability for long-running applications. Additionally, there are some refactorings to executor management and test code cleanup.

New Feature: Automatic Token Refresh

• Added support for the switcher.autorefreshtoken property, allowing the client to automatically refresh the API token before expiration. This includes updates to the configuration, builder, and property handling (README.md, SwitcherConfig.java, ContextBuilder.java, SwitcherPropertiesImpl.java, ContextKey.java). [1] [2] [3] [4] [5] [6]

• Implemented a scheduled executor service and logic in ClientRemoteService to handle token refresh, including scheduling, cancellation, and error handling. The service schedules a token refresh shortly before expiry if auto-refresh is enabled (ClientRemoteService.java, SwitcherContextBase.java, WorkerName.java). [1] [2] [3] [4] [5] [6] [7] [8] [9]

Executor Service and Refactoring

• Refactored snapshot and token refresh executor management for clarity and separation of concerns, including new executor fields, initialization methods, and termination logic in SwitcherContextBase and related files. [1] [2] [3] [4] [5]

Configuration and Documentation

• Updated the README.md to document the new switcher.autorefreshtoken property and fixed a minor formatting issue in the configuration table. [1] [2]

• Bumped the project version to 1.10.0-SNAPSHOT in pom.xml.

Testing and Minor Fixes

• Simplified test setup and teardown methods by calling helper methods directly, improving readability in several test classes. [1] [2] [3] [4] [5]

• Added a getter for the exp field in AuthResponse to support the token refresh logic.

Other Improvements

• Minor bug fix in token validation logic to ensure correct silent mode handling.
