Deprecates the support for simpleclient but ensures that it can work in
conjunction with support for the latest Prometheus client
auto-configuration.
This involves breaking changes to update public classes to support the
latest Prometheus client. Deprecated support for Prometheus simpleclient
is provided in renamed classes.

Prior to this commit, Spring Boot would auto-configure a customizer that
instruments `RestTemplate` through a `RestTemplateBuilder`. This would
install a request interceptor that instrumented client exchanges for
producing metrics.
As of spring-projects/spring-framework#28341, the instrumentation is
done at the `RestTemplate` level directly using the `Observation` API.
The `Tag` (now `KeyValue`) extraction, observation name and
instrumentation behavior now lives in the Spring Framework project.
This commit updates the auto-configuration to switch from Boot-specific
Metrics instrumentation to a generic Observation instrumentation.
As a migration path, some configuration properties are deprecated in
favor of the new `management.observations.*` namespace.

This commit adds the Spring for GraphQL auto-configuration back
into Spring Boot 3.0, now that a 1.1.0 release is scheduled with the
required baseline. This release also needs GraphQL Java 19.0 as a
baseline.
Closes gh-31809
This commit introduces auto-configuration for the new Elasticsearch
clients that are based upon their new Java client. The new Java
client builds on top of their existing low-level REST client,
replacing the high-level REST client which has been deprecated.
As part of introducing support for the new Elasticsearch client,
the auto-configuration for the templates (both imperative and
reactive) provided by Spring Data has also been updated to use the
new templates that build upon the new Java client.
As part of these changes, support for the high-level REST client and
the old Spring Data Elasticsearch templates has been removed. One
significant change is that the new reactive template is no longer
based on WebClient. As a result, the WebClient-specific configuration
property has been removed.

- Adds a ObservationRegistry bean
- Add support for ObservationRegistryCustomizers
- Enables timer creation for observations if micrometer-core is on
the classpath
- Registers ObservationPredicate, GlobalTagsProvider and
ObservationHandler on the MeterRegistry
- Applies grouping to the ObservationHandlers: MeterObservationHandler
are added to a FirstMatchingCompositeObservationHandler
- If micrometer-tracing is on the classpath, the
TracingObservationHandler are added to a
FirstMatchingCompositeObservationHandler
Closes gh-29666
Micrometer duplicated the binders in a separate module named
micrometer-binders, and marked the binders in the core module as
deprecated. This commit changes the imports to use the new binders in
the micrometer-binders module. Additionally, the auto-configurations
honor user-supplied beans which use the old binders in the
micrometer-core module.

As Spring Framework removed support for RxJava 1.x and 2.x, we should do
the same and only provide dependency management for RxJava 3.x.
Closes gh-28212
This commit adds the required infrastructure for instrumenting the
GraphQL engine and datafetchers in order to collect metrics.
With this infrastructure, we can collect metrics such as:
* "graphql.request", a timer for GraphQL query
* "graphql.datafetcher", a timer for GraphQL datafetcher calls
* "graphql.request.datafetch.count", a distribution summary of
datafetcher count per query
* "graphql.error", an error counter
See gh-29140
