- Do initial listing and syncing to scrape manager, then register event
handlers may lost events happening in listing and syncing (if it
lasted a long time). We should register event handlers at the very
begining, before processing just wait until informers synced (sync in
informer will list all objects and call OnUpdate event handler).
- Use a queue then we don't block event callbacks and an object will be
processed only once if added multiple times before it being processed.
- Fix bug in `serviceUpdate` in endpoints.go, we should build endpoints
when `exists && err == nil`. Add `^TestEndpointsDiscoveryWithService`
tests to test this feature.
Testing:
- Use `k8s.io/client-go` testing framework and fake implementations which are
more robust and reliable for testing.
- `Test\w+DiscoveryBeforeRun` are used to test objects created before
discoverer runs
- `Test\w+DiscoveryAdd\w+` are used to test adding objects
- `Test\w+DiscoveryDelete\w+` are used to test deleting objects
- `Test\w+DiscoveryUpdate\w+` are used to test updating objects
- `TestEndpointsDiscoveryWithService\w+` are used to test endpoints
events triggered by services
- `cache.DeletedFinalStateUnknown` related stuffs are removed, because
we don't care deleted objects in store, we only need its name to send
a specical `targetgroup.Group` to scrape manager

This commit avoids passing the full scrape configuration down to the
scrape loop to fix data races when the scrape configuration is being
reloaded.

This attempts to close#3973.
Handles cases where the length of the input vector to an aggregate topk
/ bottomk function is less than the K paramater. The change updates
Prometheus to allocate a result vector the same length as the input
vector in these cases.
Previously Prometheus would out-of-memory panic for large K values. This
change makes that unlikely unless the size of the input vector is
equally large.

`validateBlockSequence` is not exported, make the letter case in the comment match the function name.

Fix race by properly locking access to scrape pools. Use separate mutex for information needed by UI so that UI isn't blocked when targets are being updated.
