installing an agent on each node and sending traces to localhost.

The module `jagertracer-configurator` provides a default implementation for
setting up Jaeger Tracer. Enable the module with either system property
`-Dsolr.modules=jaegertracer-configurator` or environment variable
`SOLR_MODULES=jaegertracer-configurator`.

This is an improvement to the binary release artifact, but Jetty does not
allow web-apps (Solr) to share these libraries by default.
The `server/contexts/solr-jetty-context.xml` now explicitly removes these
restrictions, allowing Solr to share these "server" jars which now live in
`server/lib/ext`.
+=== Tracing
+* A new `opentelemetry` module is added, with support for OTEL tracing in
`OTLP` format using gRPC.
+ At the same time, the `jaegertracer-configurator` module is deprecated for
removal in Solr 10.
+ Users should start migrating to the new module to prepare for a smooth
transition.
+
== Solr 9.1
=== Querying and Indexing
* Added Lucene91HnswVectorsFormat codec for DenseVectorField. In order to use
the new codec, reindex is necessary.
