Tariq Ibrahim 8fdfa8abea refine error handling in prometheus (#5388)
i) Uses the more idiomatic Wrap and Wrapf methods for creating nested errors.
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

* *: use latest release of staticcheck

It also fixes a couple of things in the code flagged by the additional
checks.

* Use official release of staticcheck

Also run 'go list' before staticcheck to avoid failures when downloading packages.

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.

Julius Volz 099df0c5f0 Migrate "golang.org/x/net/context" -> "context" (#3333)
In some places, where ctxhttp or gRPC are concerned, we still need to use the
