Add support mongodb driver sync 5.x

[burl21]

We have noticed that spans are not being created for MongoDB, and according to the documentation, support is currently available only for MongoDB Driver v3 and v4.

@Bean
// Micrometer
MongoClientSettingsBuilderCustomizer mongoMetricsSynchronousContextProvider(
    ObservationRegistry registry) {
  return (clientSettingsBuilder) ->
      clientSettingsBuilder
          .contextProvider(ContextProviderFactory.create(registry))
          .addCommandListener(new MongoObservationCommandListener(registry));
  }

Stack

• spring boot v3.4.2
• mongodb driver sync v5.2.1
• Elastic APM agent v1.52.1
• Jdk v23

As an alternative, this is supported by OpenTelemetry instrumentation, even if there is no explicit instrumentation for 5.x, the 4.x version seems to remain. While I did not run an exhaustive test, the initial testing with a simple spring-boot example application worked as expected with dedicated spans for MongoDB, so I think we can assume it should work for most cases.

That means using any of the following agents for instrumentation allows to work-around this limitation.

• Elastic distribution, aka EDOT https://github.com/elastic/elastic-otel-java
• OpenTelemetry instrumentation https://github.com/open-telemetry/opentelemetry-java-instrumentation
