This also fixes a bug in query_log_file, which now is relative to the config file like all other paths.

The Kubernetes client records workqueue duration and latency metrics as
seconds so there's no need to convert the values from microseconds to
seconds anymore.
The cache metrics (prometheus_sd_kubernetes_cache_*) are removed because
they aren't used anymore by the client though still exposed by its API.

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

Currently Prometheus requests show up with a UA of Go-http-client/1.1
which isn't super helpful. Though the X-Prometheus-Remote-* headers
exist they need to be explicitly configured when logging the request in
order to be able to deduce this is a request originating from
Prometheus. By setting the header we remove this ambiguity and make
default server logs just a bit more useful.
This also updates a few other places to consistently capitalize the 'P'
in the user agent, as well as ensure we set a UA to begin with.

* tidy up the discovery logs,updating loops and selects
few objects renamings
removed a very noise debug log on the k8s discovery. It would be usefull
to show some summary rather than every update as this is impossible to
follow.
added most comments as debug logs so each block becomes self
explanatory.
when the discovery receiving channel is full will retry again on the
next cycle.

Especially for Kubernetes SD, this fixes a bug where the rendered
configuration says "api_server: null", which when read back is not
interpreted as an un-set API server (thus the default is not applied).

- 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
