discovery(k8s): add metadata labels to endpointslices
This commit adds 2 new metadata labels for the endpointslice role:
* `__meta_kubernetes_endpointslice_endpoint_node_name`
* `__meta_kubernetes_endpointslice_endpoint_zone`

The latter is only present when the `discovery.k8s.io/v1` API group is
available.

I also updated the configuration doc and added an entry for the
`__meta_kubernetes_endpointslice_endpoint_hostname` label which was
missing.

parser: remake generated_parser output (#13923)
In a previous PR, the generated parser was created using an old version of goyacc.

Also adds -l to disable line directives, which fixes debug processing and reduces diffs at the expense of making it more difficult to reason about the generated output.

Giedrius Statkevičius 3b8fe00767 tsdb/wlog: unregister metrics on WL close
Thanos can create and destroy TSDBs dynamically, and once a TSDB
disappears its files are deleted. Calculating the size of the
WAL then fails with errors like:

```
msg: "Failed to calculate size of "wal" dir", "err": "lstat
/tsdbdir/wal: no such file or directory", "caller": "wlog.go:271"
```

beorn7 f07f4f293f List Prometheus v3 coordinators in MAINTAINERS.md
The Prometheus v3 coordinators are full members of the Prometheus GH
org, a status that our governance specifies for maintainers. As
discussed, it appears best to formalize maintainership by listing the
coordinators in the MAINTAINERS.md file of prometheus/prometheus.

Stop compactions if there's a block to write (#13754)
* Stop compactions if there's a block to write

db.Compact() checks if there's a block to write with HEAD chunks before calling db.compactBlocks().
This is to ensure that if we need to write a block then it happens ASAP, otherwise memory usage might keep growing.

But what can also happen is that we don't need to write any block, we start db.compactBlocks(),
compaction takes hours, and in the meantime HEAD needs to write out chunks to a block.

This can be especially problematic if, for example, you run Thanos sidecar that's uploading block,
which requires that compactions are disabled. Then you disable Thanos sidecar and re-enable compactions.
When db.compactBlocks() is finally called it might have a huge number of blocks to compact, which might
take a very long time, during which HEAD cannot write out chunks to a new block.
In such case memory usage will keep growing until either:
- compactions are finally finished and HEAD can write a block
- we run out of memory and Prometheus gets OOM-killed

This change adds a check for pending HEAD block writes inside db.compactBlocks(), so that
we bail out early if there are still compactions to run, but we also need to write a new
block.

Also add a test for compactBlocks.

The existing aggregation function is very long and covers very different

`aggregationCountValues` is just for `count_values`, which differs from
other aggregations in that it outputs as many series per group as there
are values in the input.

Remove the top-level switch on string parameter type; use the same `Op`
check there as elswehere.

Pull checking parameters out to caller, where it is only executed once.
