The aggregation group is already responsible for removing the resolved alerts. Running the garbage collection in parallel introduces a race and eventually resolved notifications may be dropped. Signed-off-by: Simon Pasquier <spasquie@redhat.com>

This commit removes the GC and callback function from store.go to address a number of data races that have occurred in the past (prometheus#2040 and prometheus#3648). The store is no longer responsible for removing resolved alerts after some elapsed period of time, and is instead deferred to the consumer of the store (as done in prometheus#2040 and prometheus#3648).

I couldn't find a way to add a test since the first GC happened after 15min. I have a script to reproduce the issue and I've verified that the issue is gone after this change. The script goes like:
