[Enhancement] Make running from file not random

[OSHW-Rico]

Very useful tool!

It would be nice if it is possible to run from a file but with a non random select of the request.

I am using baton for testing insertion of big batches. I would like to see if some entries are missing in the database afterwards. But this is only possible if every entry in the list is only send once or at least in a linear way. But not with random selection of the request.
