Problem

We want to be able to skip random partitioning (i.e. overflow) entirely for capture and let plugin-server take the wheel here. See #20945 for more details, #20945 (comment) in particular.

Changes

  • Adds CAPTURE_ALLOW_RANDOM_PARTITIONING setting to support wholesale disabling of random partitioning (i.e. null key overflow routing) for analytics events.

Does this work well for both Cloud and self-hosted?

Yes, no impact -- defaults to existing behavior for now.

How did you test this code?

Updated existing test to cover the new setting in both states.

Love me some parens, and also bringing kafka_partition_key down here.
