Batch read/set/delete/add command

[ABridoux]

Describe your idea briefly.
Offer the possibility to batch read, set, delete or add a value in the data.

Describe the solution you'd like
It's possible with Scout 3.0.0 to list the paths in the data. Thus, to read, set, delete or add value on those paths. But this is not efficient when the same value has to be set on all paths, since the program will be called repeatedly.

Additional context
The command could look like scout batch set movies[:].title="New title"
