Lukasz Mierzwa 7694c89497 Increase TestHangingNotifier timeout
This test keeps timing out on our arm64 CI server, it does use a very slow timeout and that 5ms doesn't seem to be enough.
But it 10x.

machine424 690de487e2 chore(notifier): Split 'Run()' into two goroutines: one to receive target updates and trigger reloads and the other one to send notifications.
This is done to prevent the latter operation from blocking/starving the former, as previously, the `tsets` channel was consumed by the same goroutine that consumes and feeds the buffered `n.more` channel, the `tsets` channel was less likely to be ready as it's unbuffered and only fed every `SDManager.updatert` seconds.

See https://github.com/prometheus/prometheus/issues/13676 and https://github.com/prometheus/prometheus/issues/8768

The synchronization with the sendLoop goroutine is managed through the n.mtx mutex.

This uses a similar approach than scrape manager's efbd6e41c5/scrape/manager.go (L115-L117)

The old TestHangingNotifier was replaced by the new one to more closely reflect reality.

machine424 94d28cd6cf chore(notifier): add a reproducer for https://github.com/prometheus/prometheus/issues/13676
to show "targets groups update" starvation when the notifications queue is full and an Alertmanager
is down.

The existing `TestHangingNotifier` that was added in https://github.com/prometheus/prometheus/pull/10948 doesn't really reflect the reality as the SD changes are manually fed into `syncCh` in a continuous way, whereas in reality, updates are only resent every `updatert`.

The test added here sets up an SD manager and links it to the notifier. The SD changes will be triggered by that manager as it's done in reality.

Simon Pasquier 8bd6ae1b20 Notifier: fix deadlock when zero alerts
When all alerts were dropped after alert relabeling, the `sendAll()`
function didn't release the lock properly which created a deadlock with
the Alertmanager target discovery.

In addition, the commit detects early when there are no Alertmanager
endpoint to notify to avoid unnecessary work.

*: avoid missed Alertmanager targets (#6455)
This change makes sure that nearly-identical Alertmanager configurations
aren't merged together.

The config's identifier was the MD5 hash of the configuration serialized
to JSON but because `relabel.Regexp` has no public field and doesn't
implement the JSON.Marshaler interface, it was always serialized to
"{}".

In practice, the identifier can be based on the index of the
configuration in the list.
