feat: enhanced performance when async (throttle) (#399)

[petruki]

This pull request introduces several improvements and refactorings to the Switcher client. The main changes focus on dependency management, thread usage for async operations, and code simplification for better readability and performance.

Dependency updates:

• Updated the test dependency in pom.xml to use mockwebserver3-junit5 instead of separate okhttp and mockwebserver dependencies, streamlining test dependencies.
• Bumped the project version in pom.xml from 1.10.0 to 1.10.1-SNAPSHOT to reflect ongoing development.

Async execution improvements:

• Changed the executor in AsyncSwitcher from a cached thread pool to a single-threaded executor to avoid unnecessary thread creation and improve resource management.
• Refactored the execute() method in AsyncSwitcher to reduce redundant calls to System.currentTimeMillis() and improve logging clarity.

Code simplification and cleanup:

• Simplified null checks in SwitcherRequest by replacing Objects.isNull/Objects.nonNull with direct null comparisons, and improved bypass logic for clarity and efficiency. [1] [2]
