feat: set limit on store responses

[alrevuelta]

Problem

Store nodes have no limits on the amount of requests they process (in terms of req/s or served bytes/s per peer)

Suggested solution

Set limits on how many requests/second and/or bytes/second a store node can serve to each peer

Idea from offsite: use token bucket in chronos to rate limit. Should be simple to do and provide basic request rate limiting. May need more sophisticated solution to also limit e.g. response size allocation per client.

Might be duplicated in node bandwidth management issue #2032
