Overhaul `HealthEndpoint` support to make it easier to support health groups. Prior to this commit the `HealthIndicator` interface was used for both regular indicators and composite indicators. In addition the `Health` result was used to both represent individual, system and composite health. This design unfortunately means that all health contributors need to be aware of the `HealthAggregator` and could not easily support heath groups if per-group aggregation is required. This commit reworks many aspects of the health support in order to provide a cleaner separation between a `HealthIndicator`and a composite. The following changes have been made: - A `HealthContributor` interface has been introduced to represent the general concept of something that contributes health information. A contributor can either be a `HealthIndicator` or a `CompositeHealthContributor`. - A `HealthComponent` class has been introduced to mirror the contributor arrangement. The component can be either `CompositeHealth` or `Health`. - The `HealthAggregator` interface has been replaced with a more focused `StatusAggregator` interface which only deals with `Status` results. - `CompositeHealthIndicator` has been replaced with `CompositeHealthContributor` which only provides access to other contributors. A composite can no longer directly return `Health`. - `HealthIndicatorRegistry` has been replaced with `HealthContributorRegistry` and the default implementation now uses a copy-on-write strategy. - `HealthEndpoint`, `HealthEndpointWebExtension` and `ReactiveHealthEndpointWebExtension` now extend a common `HealthEndpointSupport` class. They are now driven by a health contributor registry and `HealthEndpointSettings`. - The `HealthStatusHttpMapper` class has been replaced by a `HttpCodeStatusMapper` interface. - The `HealthWebEndpointResponseMapper` class has been replaced by a `HealthEndpointSettings` strategy. This allows us to move role related logic and `ShowDetails` to the auto-configure module. - `SimpleHttpCodeStatusMapper` and `SimpleStatusAggregator` implementations have been added which are configured via constructor arguments rather than setters. - Endpoint auto-configuration has been reworked and the `CompositeHealthIndicatorConfiguration` class has been replaced by `CompositeHealthContributorConfiguration`. - The endpoint JSON has been changed make `details` distinct from `components`.
