Julien Pivotto 3677d61a4b Update kubernetes dependencies
A new API is available for AddEventHandlers, to get errors but also be
able to cancel handlers.

Doing the easy thing for the release, which is just to log errors.

We could see how to improve this in the future to handle the errors
properly and cancel the handlers.

Robert Fratto 823d24d1e9 discovery/kubernetes: add container image as metadata
This commits adds a __meta_kubernetes_pod_container_image as a new
metadata label. This can be used to alert on mismatched versions of
targets who don't have a build_info metric, as well as injecting it into
log lines for other consumers of discovery/kubernetes (e.g., Promtail).

kubernetes_sd: Allow attaching node labels for endpoint role
The Kubernetes service discovery can only add node labels to
targets from the pod role.

This commit extends this functionality to the endpoints and
endpointslices roles.

ii) Fixes some incorrect usages of fmt.Errorf where the error messages don't have any formatting directives.
iii) Does away with the use of fmt package for errors in favour of pkg/errors

Damien Lespiau e64037053d Expose controller kind and name to labelling rules
Relabelling rules can use this information to attach the name of the controller
that has created a pod.

In turn, this can be used to slice metrics by workload at query time, ie.
"Give me all metrics that have been created by the $name Deployment"

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

pasquier-s bde64cf5a6 Fix Kubernetes endpoints SD for empty subsets (#3660)
* Fix Kubernetes endpoints SD for empty subsets

When an endpoints object has no associated pods (replica scaled to zero
for instance), the endpoints SD should return a target group with no
targets so that the SD manager propagates this information to the scrape
manager.

Fixes #3659

* Don't send nil target groups from the Kubernetes SD

This is to be consistent with the endpoints SD part.
