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).

This commit removes the GC and callback function from
store.goto address a number of data races and deadlocks that have occurred in the past (#2040 and #3175). 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 #2040). This change avoids situations where the callback function for the store attempts to acquire a mutex onAbut another goroutine holds the mutex forAand needs to acquire the mutex in the store, causing a deadlock.
