feat(redis): do not update rate limit counters

[e11sy]

Problem

In the collector part we don't really know whether event would be stored into the db or not (that leads to but related to sentry events)

bug desc

collector gets all of the envelopes from sentry, it treats them as events and increments rateLimit counter in redis, however this envelope after parsing in sentry worker could be of type log, session, transaction etc.

we do not know how to process this types of the events, so we just skip them and never show to user

but rateLimit counter and chart counter were incremented by that event — here user is confused, because he can see events on the chart, or user is facing rate limit exceeded response, but he sees empty project overview

Solution

In the collector rateLimit counter becomes read-only — so we update this counter in grouper where we can't skip event, and guarantee that it would be stored to the db

Chart counter and rate limit counter updates are moved from collector to grouper
