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).

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"
