The Elasticsearch transport client has been deprecated since Spring Boot
2.2.0 and is about to be removed from Spring Data Elasticsearch and
Elasticsearch itself in their next major releases.
The available REST client support variants are now the preferred way of
using Elasticsearch features.

Prior to this commit, requests made by `HttpRequestInterceptor`
instances configured on `RestTemplate` would not be recorded
properly.
This commit ensures that nested requests are recorded separately.

Enforcing the spring-boot-dependencies platform makes for too strong
an opinion about the version of Kotlin that should be on the build
script's classpath. It clashes with the version of Kotlin that's
embedded in Gradle and used with Gradle's Kotlin DSL.
This commit switches to a normal platform (rather than an enforced
platform) which allows it to express an opinion about the version of
Kotlin without making it a strict requirement.
Closes gh-19609
This commit removes the validation starter from the web and
webflux starters - we've reconsidered that choice since many were
not using this feature as part of their default web experience.
Thit commit also changes the default EL implementation for the
Jakarta implementation, aligning all servers on it and simplifying
dependency management (especially exclusions that were required
previously).
Closes gh-19550
Prior to this commit, HTTP client builders auto-configured by Spring
Boot would be eagerly instantiating resources, even if those were not
used by the application.
This commit makes the `RestTemplateBuilder` bean as Lazy.
`WebClient.Builder` was already a prototype bean, but some of its
dependencies could consume resources, like the `HttpClientConnector` and
the related infrastructure. This commit makes those pieces lazy.
Note that since those components are meant to help instantiate actual
HTTP clients for application components, making them lazy won't make any
difference at runtime since they'll be used during context refresh, or
they won't be used at all.
Closes gh-19549
