Currently, running promtool tsdb analyze with the --extended flag
will cause an 'index out of range' error if running it
against a block that does not have any native histogram chunks.
This change ensures that promtool won't try to display data that doesn't exist.

When a rule group changes or prometheus is restarted we need to ensure we restore the active alerts that were firing for a corresponding rule, for that Prometheus uses the `ALERTS_FOR_STATE` series to query the previous state and restore it. If a given rule has high cardinality (think 100s of 1000s for series) this proccess can take a bit of time - this is the first of a series of PRs to improve this problem and I'd like to start with exposing the time it takes to restore a rule group as a gauge.

This keeps the old "react-app" directory in its existing location (to make
it easier to merge changes from the main branch), but separates it from the
npm workspaces setup. Thus it now needs to be npm-installed/built/linted
separately. This is a bit hacky, but should only be needed temporarily,
until the old UI can be removed.

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.

use it in loadDataAsQueryable to make sure the RO Head doesn't truncate or cut new chunks in data/chunks_head/.
add a -sandbox-dir-root flag to "promtool tsdb dump/dump-openmetrics" to control the root of that sandbox dirrectory.

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.

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"
```

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.
