Checking policy rules before pulling resources

[amirmalka]

Overview

This PR introduces two changes:

1. Checking the compatibility of policy rules will be called before pulling K8s resources. This fixes a bug where Kubescape tries to pull resources based on rules which should not run, either due to Kubescape version mismatch or incompatible scanning scope.

2. Failing to pull some K8s (either due to RBAC-related issue or any other error) should not fail the entire scan. In the new behavior, errors will be logged but will not interrupt the scan, unless Kubescape wasn't able to pull any resource.
