This adds a property to provide some indicator that a set of
applications are part of a larger "business application" so that they
can be viewed in metrics, portals, traces and more.

Prior to this commit, applications could declare Actuator Endpoints
using web framework-specific annotations, such as `@ServletEndpoint`,
@ControllerEndpoint and @RestControllerEndpoint.
Such annotations are closely tied to the programming model of specific
web technologies, such as Servlet or Spring MVC. Unlike other
`@Endpoint` support, they are not portable and will not work
transparently over blocking/reactive and transports.
Because of the strong adherence of this support with the underlying
infrastructure, it makes it impossible to evolve the implementation of
Actuator support without breaking this use case. The reference
documentation has been advocating for using `@Endpoint` and
`@*Operation` for custom endpoints for a long time now.
This commit deprecates this specific support in favor of the recommended
approach.
Closes gh-31768
Docs related to gh-33280 (log correlation) and
gh-35593 (application name in each log line) need some polishing:
- Fix project names
- Show how to avoid having the application name duplicated in logs
- Call out that a trailing space is needed in the correlation pattern
Closes gh-36035

Update Logback and Log4J2 so that they include the application name on
each log line. If `spring.application.name` had not been set, or if
`logging.include-application-name` is `false` then the name is not
logged.
Closes gh-35593
Rename `/actuator/httptrace` to `/actuator/httpexchanges` to better
describe its purpose and to remove confusion with distribute tracing.
This change also takes the opportunity to improve the code by making
the `HttpExchange` class (previously `HttpTrace`) fully immutable.
Closes gh-32885

As htttpclient 4.x is not supported anymore by `RestTemplate`, this
commit changes such dependencies to httpclient5 instead. In some cases,
the httpclient 4.x was transitively brought by a non-Spring dependency.

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.
