K8SPS-241: Set OPERATOR_NS in default Jenkins pipeline

[inelpandzic]

CHANGE DESCRIPTION

Problem:
Set OPERATOR_NS in the default Jenkins pipeline.

Note

• Now percona-server-mysql-orchestrator service account is created by the operator instead of with applying bundle.yaml. Because of this, the operator needs permissions for managing serviceaccounts, roles and roleBindings. We added those with additional kubebuilder annotations to the PS controller.
• version-services objects in tests (deploymen and service objects) are now checked with kubectl assert , just like the operator deployment, since it is deployed in ps-operator namespace.
• Added remove-cluster-gracefully step to all of the tests (and renamed drup-finalizer step) - this is the bulk of the PR.
