Noah Perks Sloan d0aa4a3bdd refactor: inline config as a flag 
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:
 ...
```

cedric lamoriniere 369470d6ea builder.WithGenerateStoreFunc() is now mandatory 
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`

Add auto detecting of sharding 
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.
