* config: set target group source index during unmarshalling

Fixes issue #4214 where the scrape pool is unnecessarily reloaded for a

Yecheng Fu 8ceb8f2ae8 Refactor Kubernetes Discovery Part 2: Refactoring
- Do initial listing and syncing to scrape manager, then register event
  handlers may lost events happening in listing and syncing (if it
  lasted a long time). We should register event handlers at the very
  begining, before processing just wait until informers synced (sync in
  informer will list all objects and call OnUpdate event handler).
- Use a queue then we don't block event callbacks and an object will be
  processed only once if added multiple times before it being processed.
- Fix bug in `serviceUpdate` in endpoints.go, we should build endpoints
  when `exists && err == nil`. Add `^TestEndpointsDiscoveryWithService`
  tests to test this feature.

Testing:

- Use `k8s.io/client-go` testing framework and fake implementations which are
  more robust and reliable for testing.
- `Test\w+DiscoveryBeforeRun` are used to test objects created before
  discoverer runs
- `Test\w+DiscoveryAdd\w+` are used to test adding objects
- `Test\w+DiscoveryDelete\w+` are used to test deleting objects
- `Test\w+DiscoveryUpdate\w+` are used to test updating objects
- `TestEndpointsDiscoveryWithService\w+` are used to test endpoints
  events triggered by services
- `cache.DeletedFinalStateUnknown` related stuffs are removed, because
  we don't care deleted objects in store, we only need its name to send
  a specical `targetgroup.Group` to scrape manager

Philippe Laflamme 2aba238f31 Use common HTTPClientConfig for marathon_sd configuration (#4009)
This adds support for basic authentication which closes #3090

The support for specifying the client timeout was removed as discussed in https://github.com/prometheus/common/pull/123. Marathon was the only sd mechanism doing this and configuring the timeout is done through `Context`.

DC/OS uses a custom `Authorization` header for authenticating. This adds 2 new configuration properties to reflect this.

Existing configuration files that use the bearer token will no longer work. More work is required to make this backwards compatible.

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.

Pedro Araújo 575f665944 Add OS type meta label to Azure SD (#3863)
There is currently no way to differentiate Windows instances from Linux
ones. This is needed when you have a mix of node_exporters /
wmi_exporters for OS-level metrics and you want to have them in separate
scrape jobs.

This change allows you to do just that. Example:

```
  - job_name: 'node'
    azure_sd_configs:
      - <azure_sd_config>
    relabel_configs:
      - source_labels: [__meta_azure_machine_os_type]
        regex: Linux
        action: keep
```

The way the vendor'd AzureSDK provides to get the OsType is a bit
awkward - as far as I can tell, this information can only be gotten from
the startup disk. Newer versions of the SDK appear to improve this a
bit (by having OS information in the InstanceView), but the current way
still works.

manager.
