jcli could allow some form of list preprocessing

[NicolasDP]

both /leaders/logs and fragment/logs returns a list of events that is not sorted or does not allow easy filtering.

• something simple to start with could be to add to both of these commands a --sort-by=PARAM which would sort the list by decreasing order on the PARAM field of the item.
• something else could be added: filter, that's more complicated because there is some form of more complex DSL to add. However one could start with the usual --last-updated-within='20min 39s' (there is a type for this kind of duration in jormungandr-lib::time).

🤔 Adding pagination to this logs processing would be pretty nice too.

I do have a question though, wouldn't sorting by any param be problematic ? given the fact that most of the params are strings would be sorted lexicographically and might cause issues ?

Also QQ when referring to fragment/logs through the CLI we are referring to messages ??
