Prior to this commit, the Actuator instrumentation for WebFlux servers
would not record metrics in two cases:
* the client disconnects before the response has been sent
* a server timeout is triggered before the response is sent
This commit improves the existing instrumentation to record metrics in
these cases. Since the causes of timeouts/disconnections can vary a lot,
the chosen "outcome" tag for metrics is "UNKNOWN".

Update `AbstractWebMvcEndpointHandlerMapping` to chain any caught
InvalidEndpointRequestExceptions so that a more complete stacktrace
is available. The exception has also been updated to a
`ResponseStatusException` so that the reason can be propagated.

Previously, the auto-configuration for DataSource initialization and
the properties used to configure it were part of the general
DataSource auto-configuration and properties.
This commit moves the auto-configuration of DataSource initialization
out into a separate top-level auto-configuration class. Similarly,
the properties for configuring DataSource initialization have been
moved from `spring.datasource.*` into `spring.sql.init.*`.
The old initialization-related `spring.datasource.*` properties have
been deprecated but can still be used. When they are used, they new,
separate initialization auto-configuration will back off. In other
words, the initialization related `spring.datasource.*` properties
and the `spring.sql.init.*` properties cannot be used in combination.

Previously, a root URI configured via RestTemplateBuilder's rootUri
method and RootUriTemplateHandler was not taken into account when
generated the URI tag for RestTemplate request metrics.
This commit updates MetricsClientHttpRequestInterceptor to be aware
of RootUriTemplateHandler and capture the URI template once the
root URI has been applied.
Fixes gh-25744
Refine the new `Producible` support so that it can also be used with
`@ReadOperation`, `@WriteOperation` and `@DeleteOperation` annotations.
This update allows the same enum to be used both as an argument and as
an indicator of the media-types that an operation may produce.
Closes gh-25738
Update the actuator @Enpoint` infrastructure code so that operations
may inject enums that indicate the type of output to produce. A new
`Producible` interface can be implemented by any enum that indicates
the mime-type that an enum value produces.
The new `OperationArgumentResolver` provides a general strategy for
resolving operation arguments with `ProducibleOperationArgumentResolver`
providing support for `Producible` enums. Existing injection support has
been refactored to use the new resolver.

This commit modifies the actuator `EnvironmentEndpoint` to allow
primitive wrapper types to be serialized in the response data
structure.
Fixes gh-24307
When `EnvironmentEndpoint` is building a response to return to the
web infrastructure, it creates a data structure containing all
property values from all property sources. Prior to this commit, it
was possible for the response data structure to contain property
values that were not serializable to JSON by Jackson, which would
cause an exception to be thrown by the web infrastructure. This
commit ensures the data structure is serializable to JSON by
ensuring property values are primitives or Strings, and returning
a placeholder value if a property value is of any other type.
Fixes gh-23805
This commit adds support for Redis cache metrics. Users can opt-in for
statistics using the "spring.cache.redis.enable-statistics" property.
Closes gh-22701
Constructor calls like new AtomicInteger(0) cause a volatile write that
can be saved in cases where the constructor parameter is the default
value.
