This commit optimizes the `Tag` generation for method names by only
allocating new `Tag` instances for well-known method names. Others will
be marked as "UNKNOWN".
This commit knowingly makes breaking API changes to
JerseyHealthEndpointAdditionalPathResourceFactory. We considered
other options but they all had the potential to be backwards
incompatible in one way or another. Faced with that situation we
concluded that the likelihood of anyone using the modified API
directly is small enough to warrant making the breaking changes.
If it becomes apparent that we have misjudged things we can revisit
the changes in the future.
Closes gh-36250
Support custom Log4J2 log levels by changing `LoggerConfiguration` so
that it can now report levels using a `LevelConfiguration` object
rather than the limited `LogLevel` enum.
The `Log4J2LoggingSystem` class now uses `LevelConfiguration.ofCustom`
for custom logging levels, rather than throwing an exception.
The `LoggersEndpoint` has also been updated so that it can return the
custom logger name.
Fixes gh-35227

Spring Integration's `IntegrationGraphServer` can be used without
actuator or even Spring Boot at all. It is more natural to have
respective reflection hints exposed by Spring Integration itself.
See related GH issue and its fix which just does a migration of the
remove code from `IntegrationGraphEndpoint`.

Update `Neo4jReactiveHealthIndicator` to ensure that `result.records()`
is called before `result.consume()`. Prior to this commit, the indicator
used `zipWith` to merge records with a summary. This worked with the
previous RxJava based driver, but fails with the Reactor based driver
due to a `NoSuchElementException: Source was empty` error.
Fixes gh-33428
