Add support for health indicator groups

Browse Source 
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

==== Health Groups
It's sometimes useful to organize health indicators into groups that can be used for
different purposes. For example, if you deploy your application to Kubernetes, you may
want one different sets of health indicators for your "`liveness`" and "`readiness`"
probes.
To create a health indicator group you can use the `management.endpoint.health.group.<name>`
property and specify a list of health indicator IDs to `include` or `exclude`. For example,
to create a group that includes only database indicators you can define the following:
[source,properties,indent=0]
----
management.endpoint.health.group.custom.include=db
----
You can then check the result by hitting `http://localhost:8080/actuator/health/custom`.
By default groups will inherit the same `StatusAggregator` and `HttpCodeStatusMapper`
settings as the system health, however, these can also be defined on a per-group
basis. It's also possible to override the `show-details` and `roles` properties
if required:
[source,properties,indent=0]
----
management.endpoint.health.group.custom.show-details=when-authorized
management.endpoint.health.group.custom.roles=admin
management.endpoint.health.group.custom.status.order=fatal,up
management.endpoint.health.group.custom.status.http-mapping.fatal=500
----
TIP: You can use `@Qualifier("groupname")` if you need to register custom
`StatusAggregator` or `HttpCodeStatusMapper` beans for use with the group.
