Service configurator pattern

Description:

The Service Configurator design pattern allows an application to dynamically configure and manage a set of services without requiring a restart. This pattern is useful for applications that need to handle a variety of services with different configurations and lifecycles. Key elements of the Service Configurator pattern include service registration, dynamic configuration, lifecycle management, and service lookup.

Main elements of the Service Configurator pattern:

1. Service Registration: Services are registered with a central registry or configuration manager.
2. Dynamic Configuration: Services can be configured dynamically at runtime, allowing for changes without restarting the application.
3. Lifecycle Management: The pattern manages the lifecycle of services, including initialization, configuration, reconfiguration, and shutdown.
4. Service Lookup: Services can be located and accessed by clients through a central lookup mechanism.

Acceptance Criteria:

1. Implement a Service Configurator class that handles the registration, configuration, and lifecycle management of services.
2. Provide example services that demonstrate dynamic configuration and lifecycle management.
3. Include unit tests to verify the correct implementation of the Service Configurator pattern and its components.

No file, entry point, or existing test is named. Start by surveying the repository's existing Java design-pattern implementations, then define the Service Configurator class, example services, and unit tests; done means registration, dynamic configuration, lifecycle management, and service lookup are covered.
