Update `CompositeHandlerExceptionResolver` to search for beans in
all contexts. Note that `BeanFactoryUtils.beansOfTypeIncludingAncestors`
cannot not be used since we need to pick up all beans, even if they
have the same name.

Allow legacy actuator endpoint IDs that contain dots to be transparently
migrated to the new format. This update will allow Spring Cloud users
to proactively migrate from endpoints such as `hystrix.stream` to
`hystrixstream`.
Closes gh-18148
Update the `HealthEndpoint` to support health groups. The
`HealthEndpointSettings` interface has been replaced with
`HealthEndpointGroups` which provides access to the primary group
as well as an optional set of additional groups.
Groups can be configured via properties and may have custom
`StatusAggregator` and `HttpCodeStatusMapper` settings.
Closes gh-14022
