* refactor(kubernetes): streamline provider configuration and in-cluster detection
- Removed IsInCluster method from Manager and created function scoped to the runtime environment.
As a method, the implementation was not correct.
Removed GetAPIServerHost method from Manager which is no used.
- **Temporarily** added an `inCluster` field to the Manager struct but should be eventually removed since it doesn't really make sense to hava a Manager in-cluster or out-of-cluster in the multi-cluster scenario.
- Provider resolution (resolveStrategy) is now clearer, added complete coverage for all scenarios.
- Added additional coverage for provider and manager.
