Deprecate Micrometer Tracing code in favor of tracing in MongoDB driver

[mp911de]

We should deprecated our Micrometer Tracing implementation in favor of MongoDB's OpenTelemetry implementation in the driver. MongoObservationCommandListener.

Observation through MongoObservationCommandListener creates distributed tracing spans including context propagation and it creates long-task timers (e.g. spring.data.mongodb.command.active) that are sent to observability systems (e.g. Prometheus) using a set of tags.

Having an implementation on the Spring Data level while Spring Boot configures a different metrics implementation (see #4926) is unfortunate and that can be solved by having metrics and tracing directly within the driver.
