We add 2 new params to channel members query. 1. Filter by teamId. 2. Negate that filter. We include some more optimizations like: - Moved the team role checks inside the dataloader. - Moved the channel pretty name computation inside the loader. Now that we load less data on initial load, we can reduce the concurrency requirement to be a bit on the safer side. ```release-note NONE ```
