the `slug` is only present in the public images.
To refer a user-generated image (`snapshot` or `custom`) we can use
the image's display name.

Tom Wilkie d479151f1f Various enhancements and refactorings for remote write receiver: 
- Remove unrelated changes
- Refactor code out of the API module - that is already getting pretty crowded.
- Don't track reference for AddFast in remote write.  This has the potential to consume unlimited server-side memory if a malicious client pushes a different label set for every series.  For now, its easier and safer to always use the 'slow' path.
- Return 400 on out of order samples.
- Use remote.DecodeWriteRequest in the remote write adapters.
- Put this behing the 'remote-write-server' feature flag
- Add some (very) basic docs.
- Used named return & add test for commit error propagation

'@ <timestamp>' modifier (#8121) 
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.
