[LU-14501] NRS TBF UID: limit per "any" user?

Description

In my understanding of the TBF UID rules, it is not possible to set a limit per "any UID". In our testing, the default rule ( default {*} 10000 ) seems to include ALL UIDs, that is, 10,000 requests for all users. Please correct me if I'm wrong.

Say, we want to limit ost.OSS.ost_io.nrs_tbf_rule to 100 reqs/user. Do we have to add a rule for each UID? In our case, we have ~5,400 users.
