889dd0bbd3 Fix DB tests in the default branch 
The main branch tests are not passing due to the fact that #8489 was not
rebased on top of #8007.

Combine Appender.Add and AddFast into a single Append method. (#8489) 
This moves the label lookup into TSDB, whilst still keeping the cached-ref optimisation for repeated Appends.

This makes the API easier to consume and implement.  In particular this change is motivated by the scrape-time-aggregation work, which I don't think is possible to implement without it as it needs access to label values.

Compress records before checking segment size (#8501) 
Right now a new segment might be created unnecessarily if the
uncompressed record would not fit, but after compression (typically
reducing record size in half) it would.

75d86c6747 Update golangci-lint to 1.36.0 
In the previous version, 1.18.0, the "megacheck" linter paid attention
to the '//lint:ignore' comment, but that is no longer there.

Newer version pay attention to '//nolint:<linter>,<linter>,...'
comments, optionally followed by a "second" comment introduced by '//'.

Update the directives to use this style.

This is related to prometheus/blackbox_exporter#738 and
prometheus/blackbox_exporter#745.

Increase the buckets for compaction duration (#8342) 
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.

MultiError: Refactored MultiError for more concise and safe usage. (#8066) 
* MultiError: Refactored MultiError for more concise and safe usage.

* Less lines
* Goland IDE was marking every usage of old MultiError "potential nil" error
* It was easy to forgot using Err() when error was returned, now it's safely assured on compile time.

NOTE: Potentially I would rename package to merrors. (: In different PR.
