ConnectionTypeVisitor to decorate DataFetchers for Connection fields
in order to adapt Window, Slice, and others to Connection.
A ScrollRequest controller method argument to inject the ScrollPosition
and the number of elements requested.
SortStrategy for an application to customize how to extract sort
details from GraphQL arguments.

Prior to this commit, using the tracing support could result in an
NullPointerException since the instrumentation expected the tracing
propagation information to be always available from the request
extensions.
This commit improves the strategy for extracing the inbound propagation
information.
First, the instrumentation now looks up the propagation information in
the GraphQL context first, then in the request extensions as a fallback.
We ensure that no NPE can be raised if the information is missing.
Some clients might change the propagation information in the request
extensions, but in the HTTP world, most clients will send those as HTTP
headers. We are adding a new `PropagationWebGraphQlInterceptor` that can
be configured on the application to copy the relevant HTTP headers from
the HTTP request to the GraphQL context. For other transports, we
currently advise the request extensions - both WebSocket and RSocket
multiplex over the same transport message, making this approach
impossible.
Fixes gh-547
This change aligns with the Jakarta API requirements in Spring
Framework.
This commit also upgrades optional dependencies with the latest compatible
versions.
Closes gh-543
Prior to this commit, metrics instrumentation was provided by Spring
Boot, using Micrometer metrics. The `Instrumentation` would publish two
timers and a counter, but would not support tracing.
This commit replaces the former with a dedicated support in Spring for
GraphQL directly. This uses the new `Observation` API from Micrometer
and publishes two observations:
* a request execution observation, with timing and tracing included
* a data fetching observation with the request execution as a parent
observation
Closes gh-501
