@ConditionalOnEnabledTracing is now applied to the minimal amount of
beans. The beans which are annotated with it are beans that will lead
to span sending to backends.
This leaves the majority of the Micrometer Tracing, Brave and
OpenTelemetry infrastructure untouched in tests.

Previously, when using SpringApplication.from() any additional
sources configured using with() would be applied to every
SpringApplication that was created within the scope of the call to
run(). This caused problems with Spring Cloud's bootstrap context
where the additional sources would be applied to both the user's
application and to the boostrap context's application.
This commit updates the hook that's used to apply the additional
sources so that it's only applied once. This results in the
additional sources only being added to the first SpringApplication
that is run.
Closes gh-35873
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
When Hazelcast is started on a fixed port and that port is already in
use, it does not fail to start which makes the problem hard to
detect. A symptom of the problem is that clients will not be able to
connect and will either retry indefinitely or will timeout depending
on their configuration.
This commit updates the Hazelcast client tests to start the Hazelcast
instance on an ephemeral port and to customize the client
configuration with the instance's address before use. This should
allow the client tests to work reliably in an environment where
Hazelcast's default port is already in use.
