Drop propagate_traces (#4206)

Drop the deprecated `propagate_traces` `init` option in POTel.

Important: The Celery integration also has an option called
`propagate_traces` -- this should remain unchanged.

 - Spans no longer have a `description`. Use `name` instead.
 - Dropped support for Python 3.6.
 - The `enable_tracing` `init` option has been removed. Configure `traces_sample_rate` directly.
+- The `propagate_traces` `init` option has been removed. Use `trace_propagation_targets` instead.
 - The `custom_sampling_context` parameter of `start_transaction` has been removed. Use `attributes` instead to set key-value pairs of data that should be accessible in the traces sampler. Note that span attributes need to conform to the [OpenTelemetry specification](https://opentelemetry.io/docs/concepts/signals/traces/#attributes), meaning only certain types can be set as values.
 - The PyMongo integration no longer sets tags. The data is still accessible via span attributes.
 - The PyMongo integration doesn't set `operation_ids` anymore. The individual IDs (`operation_id`, `request_id`, `session_id`) are now accessible as separate span attributes.
