Refactor several areas of the actuator endpoint code in order to make future extensions easier. The primary goal is to introduce the concept of an `ExposableEndpoint` that has technology specific subclasses and can carry additional data for filters to use. Many other changes have been made along the way including: * A new EndpointSupplier interface that allows cleaner separation of supplying vs discovering endpoints. This allows cleaner class names and allows for better auto-configuration since a user can choose to provide their own supplier entirely. * A `DiscoveredEndpoint` interface that allows the `EndpointFilter` to be greatly simplified. A filter now doesn't need to know about discovery concerns unless absolutely necessary. * Improved naming and package structure. Many technology specific concerns are now grouped in a better way. Related concerns are co-located and concepts from one area no longer leakage into another. * Simplified `HandlerMapping` implementations. Many common concerns have been pulled up helping to create simpler subclasses. * Simplified JMX adapters. Many of the intermediary `Info` classes have been removed. The `DiscoveredJmxOperation` is now responsible for mapping methods to operations. * A specific @`HealthEndpointCloudFoundryExtension` for Cloud Foundry. The extension logic used to create a "full" health endpoint extension has been made explicit. Fixes gh-11428 Fixes gh-11581
