Create presets for common needs: max throughput, minimum latency, etc

### Feature description

- Max throughput would prioritise throughput over latency: enable batching, use refetch delay (see: #500), etc
- Min latency would prioritise latency from filing a job to executing it: minimal batching, no refetch delay, etc
- High scale might be a balance of these suitable for people who are dealing with very high numbers of workers/jobs.

### Motivating example

People don't like to read documentation or have too many options; pick some sensible ones for them.

### Breaking changes

None.
