Review Comment:
doing the grouping since we want the print to look like:
`
backendWorkerToken1:
- GetWorkStream
- CommitWorkStream
- GetDataStream
backendWorkerToken2:
- GetWorkStream
- CommitWorkStream
- GetDataStream
Dispatcher:
- GetWorkerMetadata
`
etc.
if we don't group and keep it flat it will look like:
`
- backendWorkerToken1-GetWorkStream
- backendWorkerToken1-CommitWorkStream
- backendWorkerToken1-GetDataStream
- backendWorkerToken2-GetWorkStream
- backendWorkerToken2-CommitWorkStream
- backendWorkerToken2-GetDataStream
- Dispatcher-GetWorkerMetadata
`
etc.
I found the former nested view easier to read.
