Note that this depends on #6171 since it touches the schemas.txt. That PR needs to be reviewed first. Please ignore the first commit in this PR (as that belongs to that PR) and only review the second one.
The previous PR has landed.

Every request entry in thread network now has a marker handle, so a slow request can be fed straight to zoom push m-N or marker info m-N without re-finding it via thread markers. Other commands in the cli usually have marker handles if they show any markers, we didn't include that before, but it's always good to include it.

Every request entry in `thread network` now carries a marker handle, so
a slow request can be fed straight to `zoom push m-N` or `marker info
m-N` without re-finding it via `thread markers`. Threads the markerMap
through collectThreadNetwork.
