We default to a 30s scrapeInterval, we may as well also set scrapeTimeout to the same.

As requested, this updates the resource specification to live directly in config.kubeStateMetrics

It also clarifies the config variables. These names are what google uses in some of their tooling.

(And a slight tweak to the way collectors are specified)

As I work with kube-state-metrics in a large cluster, I found I needed to make some adjustments.

- Expose the collectors, allowing one to configure exclusions. 

- Expose the addon_resizer parameters, facilitating reproduce adjustments

- Allow adjusting scrapeTimeout and scrapeInterval

Allow settings custom tags of container images

kube-prometheus: Add kube-prometheus mixin to configure static etcd

kube-prometheus/Makefile: Change target output from files to folder

RemoteWriteSpec Expose QueueConfig Parameters (#1488)

Previously the `manifests` and `vendor` folder content has been build
via `manifests/**` and `vendor/**` target definitions. This results in
two issues:

1. The GNU Make recipe is executed for every single file in the folders.

2. Not all timestamps inside the `manifests` folder would be updated on
every run, thereby needing to be rerun on all following target
executions.

Solution:

1. Define the target based on the folder, not individual files

2. Remove target folder before execution recipe to ensure all timestamps
are updated.

kube-prometheus: Run node-exporter in host network

Node exporter needs to run in the host network, not in the pod network
in order to pick up network metrics of the node.

*: Refactor build system

- Move prometheus-config-reloader to cmd/
- Refactor Makefile & contrib/kube-prometheus/Makefile
- Only execute a target if its dependencies changed
  - Create empty target file for docker builds
- Replace promu with plain static `go build`
