Last change in 4efca5ab introduced a problem where NewDiscovery would
just return a nil value, which is not handled well and didn't allow for
fixing configuration issues at runtime without a reload.

Deprecate --alertmanager.timeout

We're seeing compactions that are taking hours in Cortex which this is
missing. I know while it is not common in Prometheus, I am pretty sure
there are setups where compaction takes longer than 512s. On our own
Prometheus the average compaction duration is 566s.

Merge release-2.24 forward into main branch

This commit adds `@ <timestamp>` modifier as per this design doc: https://docs.google.com/document/d/1uSbD3T2beM-iX4-Hp7V074bzBRiRNlqUdcWP6JTDQSs/edit.

An example query:

```
rate(process_cpu_seconds_total[1m]) 
  and
topk(7, rate(process_cpu_seconds_total[1h] @ 1234))
```

which ranks based on last 1h rate and w.r.t. unix timestamp 1234 but actually plots the 1m rate.
