* Correct key used to retrieve metadata from cache

When we're setting metadata entries in the scrapeCace, we're using the
p.Help(), p.Unit(), p.Type() helpers, which retrieve the series name and
use it as the cache key. When checking for cache entries though, we used
p.Series() as the key, which included the metric name _with_ its labels.
That meant that we were never actually hitting the cache. We're fixing
this by utiling the __name__ internal label for correctly getting the
cache entries after they've been set by setHelp(), setType() or
setUnit().

Add prometheus_ready metric (#10682)
When Prometheus starts it can take a long time before WAL is replayed and it can do anything useful. While it's starting it exposes metrics and other Prometheus servers can scrape it.
We do have alerts that fire if any Prometheus server is not ingesting samples and so far we've been dealing with instances that are starting for a long time by adding a check on Prometheus process uptime. Relying on uptime isn't ideal because the time needed to start depends on the number of metrics scraped, and so on the amount of data in WAL.
To help write better alerts it would be great if Prometheus exposed a metric that tells us it's fully started, that way any alert that suppose to notify us about any runtime issue can filter out starting instances.

Stop rule manager before TSDB is stopped (#10680)
During shutdown TSDB is stopped before rule manager is stopped. Since  TSDB shutdown can take a long time (minutes or 10s of minutes) it keeps rule manager running while parts of Prometheus are already stopped (most notebly scrape manager). This can cause false positive alerts to fire, mostly those that rely on absent() calls since new sample appends will stop while alert queries are still evaluated.
Stop rules before stopping TSDB and scrape manager to avoid this problem.

Add a --lint flag to the promtool check rules and check config commands (#10435)
* Add a --lint flag to the promtool check rules and check config commands

Checking rules with promtool emits warnings in the case of duplicate rules.
These warnings do not result in a non-zero exit code and are difficult to
spot in CI environments. Additionally, checking for duplicates is closer
to a lint check rather than a syntax check.

This commit adds a --lint flag to commands which include checking rules.
The flag can be used to enable or disable certain linting options
and cause the execution to return a non-zero exit code in case
those options are not met.

of stats queries can report.

We also allow optionally tracking per-step samples queried. This must be

The engine flag is exposed via a Prometheus feature flag, while the
query flag is set when stats=all.

Improve error logging for missing config and QL dir (#10260)
* Improve error logging for missing config and QL dir

Currently, when Prometheus can't open its config file or the query
logging dir under the data dir, it only logs what it has been given
default or commandline/config. Depending on the environment this can be
less than helpful, since the working directory may be unclear to the
user. I have specifically kept the existing error messages as intact as
possible to a) still log the parameter as given and b) cause as little
disruption for log-parsers/-analyzers as possible.

So in case of the config file or the data dir being non-absolute paths,
I use os.GetWd to find the working dir and assemble an absolute path for
error logging purposes. If GetWd fails, we just log "unknown", as
recovering from an error there would be very complex measure, likely not
worth the code/effort.

Example errors:

```
$ ./prometheus
ts=2022-02-06T16:00:53.034Z caller=main.go:445 level=error msg="Error loading config (--config.file=prometheus.yml)" fullpath=/home/klausman/src/prometheus/prometheus.yml err="open prometheus.yml: no such file or directory"
$ touch prometheus.yml
$ ./prometheus
[...]

beorn7 8fdfa52976 API: Promote remote-write-receiver to stable
Since `/api/v1/write` is a mutating endpoint, we should still activate
the remote-write-receiver explicitly. But we should do it in the same
way as the other mutating endpoints, i.e. via a flag
`--web.enable-remote-write-receiver`.

This commit marks the feature flag as deprecated, i.e. it still works
but logs a warning on startup. This enables users to seamlessly
migrate. With the next minor release, we can start ignoring the
feature flag (but still warn a user that is trying to use it).

zzehring 42628899b5 promtool: Add `--syntax-only` flag for `check config`
This commit adds a `--syntax-only` flag for `promtool check config`.
When passing in this flag, promtool will omit various file existence
checks that would cause the check to fail (e.g. the check would not
fail if `rule_files` files don't exist at their respective paths).

This functionality will allow CI systems to check the syntax of
configs without worrying about referenced files.
