TJ Hoplock 6ebfbd2d54 chore!: adopt log/slog, remove go-kit/log
For: #14355

This commit updates Prometheus to adopt stdlib's log/slog package in
favor of go-kit/log. As part of converting to use slog, several other
related changes are required to get prometheus working, including:
- removed unused logging util func `RateLimit()`
- forward ported the util/logging/Deduper logging by implementing a small custom slog.Handler that does the deduping before chaining log calls to the underlying real slog.Logger
- move some of the json file logging functionality to use prom/common package functionality
- refactored some of the new json file logging for scraping
- changes to promql.QueryLogger interface to swap out logging methods for relevant slog sugar wrappers
- updated lots of tests that used/replicated custom logging functionality, attempting to keep the logical goal of the tests consistent after the transition
- added a healthy amount of `if logger == nil { $makeLogger }` type conditional checks amongst various functions where none were provided -- old code that used the go-kit/log.Logger interface had several places where there were nil references when trying to use functions like `With()` to add keyvals on the new *slog.Logger type

Daniel Kimsey aa3e58358b consul: Add support for catalog list services filter
This adds support for Consul's Catalog [List Services][^1] API's `filter`
parameter added in 1.14.x. This parameter grants the operator more
flexibility to do server-side filtering of the Catalog, before
Prometheus subscribes for updates. Operators can use this to improve
both the performance of Prometheus's Consul SD and reduce the impact of
enumerating large catalogs.

Use 10m timeouts for watches (#7423)
use ?wait=10m will give results as fast as usual when data is changing
but will perform far less requests when services do not change.

On large infrastructure, this will reduce quite a lot the number of

of results.

Corentin Chary 60dafd425c consul: improve consul service discovery (#3814)
* consul: improve consul service discovery

Related to #3711

- Add the ability to filter by tag and node-meta in an efficient way (`/catalog/services`
  allow filtering by node-meta, and returns a `map[string]string` or `service`->`tags`).
  Tags and nore-meta are also used in `/catalog/service` requests.
- Do not require a call to the catalog if services are specified by name. This is important
  because on large cluster `/catalog/services` changes all the time.
- Add `allow_stale` configuration option to do stale reads. Non-stale
  reads can be costly, even more when you are doing them to a remote
  datacenter with 10k+ targets over WAN (which is common for federation).
- Add `refresh_interval` to minimize the strain on the catalog and on the
  service endpoint. This is needed because of that kind of behavior from
  consul: https://github.com/hashicorp/consul/issues/3712 and because a catalog
  on a large cluster would basically change *all* the time. No need to discover
  targets in 1sec if we scrape them every minute.
- Added plenty of unit tests.

Benchmarks
----------

```yaml
scrape_configs:

- job_name: prometheus
  scrape_interval: 60s
  static_configs:
    - targets: ["127.0.0.1:9090"]

- job_name: "observability-by-tag"
  scrape_interval: "60s"
  metrics_path: "/metrics"
  consul_sd_configs:
    - server: consul.service.par.consul.prod.crto.in:8500
      tag: marathon-user-observability  # Used in After
      refresh_interval: 30s             # Used in After+delay
  relabel_configs:
    - source_labels: [__meta_consul_tags]
      regex: ^(.*,)?marathon-user-observability(,.*)?$
      action: keep

- job_name: "observability-by-name"
  scrape_interval: "60s"
  metrics_path: "/metrics"
  consul_sd_configs:
    - server: consul.service.par.consul.prod.crto.in:8500
      services:
        - observability-cerebro
        - observability-portal-web

- job_name: "fake-fake-fake"
  scrape_interval: "15s"
  metrics_path: "/metrics"
  consul_sd_configs:
    - server: consul.service.par.consul.prod.crto.in:8500
      services:
        - fake-fake-fake
```

Note: tested with ~1200 services, ~5000 nodes.

| Resource | Empty | Before | After | After + delay |
| -------- |:-----:|:------:|:-----:|:-------------:|
|/service-discovery size|5K|85MiB|27k|27k|27k|
|`go_memstats_heap_objects`|100k|1M|120k|110k|
|`go_memstats_heap_alloc_bytes`|24MB|150MB|28MB|27MB|
|`rate(go_memstats_alloc_bytes_total[5m])`|0.2MB/s|28MB/s|2MB/s|0.3MB/s|
|`rate(process_cpu_seconds_total[5m])`|0.1%|15%|2%|0.01%|
|`process_open_fds`|16|*1236*|22|22|
|`rate(prometheus_sd_consul_rpc_duration_seconds_count{call="services"}[5m])`|~0|1|1|*0.03*|
|`rate(prometheus_sd_consul_rpc_duration_seconds_count{call="service"}[5m])`|0.1|*80*|0.5|0.5|
|`prometheus_target_sync_length_seconds{quantile="0.9",scrape_job="observability-by-tag"}`|N/A|200ms|0.2ms|0.2ms|
|Network bandwidth|~10kbps|~2.8Mbps|~1.6Mbps|~10kbps|

Filtering by tag using relabel_configs uses **100kiB and 23kiB/s per service per job** and quite a lot of CPU. Also sends and additional *1Mbps* of traffic to consul.
Being a little bit smarter about this reduces the overhead quite a lot.
Limiting the number of `/catalog/services` queries per second almost removes the overhead of service discovery.

* consul: tweak `refresh_interval` behavior

`refresh_interval` now does what is advertised in the documentation,
there won't be more that one update per `refresh_interval`. It now
defaults to 30s (which was also the current waitTime in the consul query).

This also make sure we don't wait another 30s if we already waited 29s
in the blocking call by substracting the number of elapsed seconds.

Hopefully this will do what people expect it does and will be safer
for existing consul infrastructures.
