At present, RestClientBuilderCustomizer allows general customization of RestClientBuilder.
This is troublesome for users that want to customize `HttpAsyncClientBuilder` and
`RequestConfig.Builder` since those are set on the `RestClientBuilder`. By customizing
those two builders user lose out on Spring Boot's support for binding username, password,
connection-timeout and read-timeout properties from `"spring.elasticsearch.rest"` namespace.
This commit enhances the `RestClientBuilderCustomizer` with support for customizing
`HttpAsyncClientBuilder` and `RequestConfig.Builder` by providing additional `customize`
methods that accept the aforementioned builders. Both new methods are optional as they have
no-op default implementations.

Refine `DataSourceAutoConfiguration` conditions so that an empty
`spring.datasource.url` property can be used to enable the embedded
source.
Fixed gh-20996
This commit marks as deprecated an interface method that is no longer
used, and changes all internal implementations to return `null` to
make the fact that the return value is not used more obvious.
Fixes gh-19844
Prior to this commit, default error responses included the message
from a handled exception. When the exception was a BindException, the
error responses could also include an errors attribute containing the
details of the binding failure. These details could leak information
about the application.
This commit removes the exception message and binding errors detail
from error responses by default, and introduces a
`server.error.include-details` property that can be used to cause
these details to be included in the response.

Create a general purpose `AvailabilityState` interface and refactor
the existing `LivenessState` and `ReadinessState` to use it. A single
`AvailabilityChangeEvent` is now used to carry all availability state
updates.
This commit also renames `ApplicationAvailabilityProvider` to
`ApplicationAvailabilityBean` and extracts an `ApplicationAvailability`
interface that other beans can inject. The helps to hide the event
listener method, which is really internal.
Finally the state enums have been renamed as follows:
- `LivenessState.LIVE` -> `LivenessState.CORRECT`
- `ReadinessState.READY` -> `ReadinessState.ACCEPTING_TRAFFIC`
- `ReadinessState.UNREADY` -> `ReadinessState.REFUSING_TRAFFIC`

Prior to this commit, the `HttpHandlerAutoConfiguration` would rely on
the `WebFluxProperties` bean being present - this is most of the time
true when the appplication is using the WebFlux auto-configuration.
If the application is overriding the WebFlux auto-configuration and
providing its own setup, the properties bean is not present and we
should skip its usage.
Fixes gh-20891
Rename the SAML `singleSignOn` nested property to `singleSignOn` so
that we don't get problems when using uppercase environment variable
names.
