The multiListerWatcher is a composite object encapsulating multiple
ListerWatchers and implements the ListerWatcher interface.
With the current implementation, when an individual lister fails, the
entire List operation fails. This causes no metrics to be shown when KSM
has no permissions to a single namespace.
In addition to this, the multiListerWatcher takes advantage of internal
implementation details if the client-go library by modifiying and
relying on the ResourceVersion metadata field. This introduces a bug
where reconnecting to the API server will break the multiListerWatcher
completely.
This commit replaces the multiListerWatcher with individual
ListerWatchers per each configured namespace, resolving both issues.

- Use `cache.Store` interface for genericity and extensibility.
- Add `WithCustomGenerateStoreFunc` method to `Builder` struct for allowing
custome metrics Stores generation.

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.
