The `Scope.get_client` method is typed as returning `sentry_sdk.client.BaseClient`, but because `sentry_sdk.client` was not imported, the type was resolved as `Any`. This change imports `sentry_sdk.client` to fix the type hints.

Remove MetricValue from the set metric's value type hint. MetricValue is a union that includes floatwhich is correct based on how other parts of the code uses MetricValue. However, as floats are intentionally floored for set metrics, the current type hint might be confusing for a user as it looks like floats would work as unique values in a set.

Fixes GH-3038

Send the queue name to Sentry for Celery tasks using the default exchange. The queue name is sent as span data with the key `messaging.destination.name` within a new span op named "queue.process".

Also, add tests for the new behavior.

Ref GH-2961

Send the retry count of a Celery task as a span data attribute on the "queue.process" span. Also, add tests for this feature.

Ref #2961

Set Celery task ID on the "queue.process" span, and add tests for this new behavior.

Closes #2974

Set the "messaging.system" data on the "queue.process" span in the Celery integration. The messaging.system span data attribute should be set to the Celery broker being used, e.g. "amqp" for RabbitMQ, "redis" for Redis, and "sqs" for Amazon SQS. Also, add tests for this feature.

ref #2951

This change ensures that we only propagate trace headers from spans that are within a transaction. This fixes a bug where any child transactions of a span created outside a transaction are missing a dynamic sampling context and are part of a trace missing a root transaction (because the root is the span).

Also, remove/modify tests that were asserting the old behavior.
