This is more flexible than the env variable, as a configuration can still set an env variable and use substitution in the args. e.g.,
```yaml
args:
- --custom-resource-state.config
- $(KSM_CUSTOM_RESOURCE_STATE_CONFIG)
env:
...
```
This commit introduces the fact that build.WithGenerateStoreFunc()
needs to be used for configuring properly the `Builder` (like any other
`With...` method.
* rename: `WithCustomGenerateStoreFunc` to `WithGenerateStoreFunc`.
* remove buildStorFunc defaulting in `NewBuilder()` function
* add `DefaultGenerateStoreFunc()` method in `BuilderInterface`
* update `Builder initialisation` in `main.go`

main_test.go: Add model based test for sharding
In order to ensure a sharded system behaves equal to an unsharded
system, a model based test has been introduced. It scrapes an unsharded
setup and compares its output with the union of a sharded setup
therefore ensuring semantic equality.
When kube-state-metrics does not have the correct roles to list or watch
on a resource, it just logs this error but not actually error out. This
is a problem as the pod never restars and it is hard to catch any
problems as other resource metrics continue to be created correctly. We
only see this error in the noisy kube-state-metrics logs.
This registers two metrics `kube_state_metrics_watch_total` and
`kube_state_metrics_list_total`. With the following labels:
"result" label is the type of action count relates to, error or success.
"resource" label contains the resource <apiVersion.Kind>.
This way we can do a rate alert when kube-state-metrics error rate is
too high.
Example of the metrics:
kube_state_metrics_list_total{resource="*v1.Namespace",result="success"} 1
kube_state_metrics_list_total{resource="*v1.Node",result="error"} 52
kube_state_metrics_watch_total{resource="*v1beta1.Ingress",result="success"} 1
