    Delete Kubernetes resources on application updates

    Within the application update process, it is necessary to
    call "kubectl delete -k <manifest_dir>" to delete the
    charts that will not be present in the new version of the
    application. This way we eliminate unnecessary
    remnants of secrets in the N+1 application.

    Test Plan:
    PASS: Upload/Apply/Remove/Delete cert-manager
    PASS: Upload/Apply/Remove/Delete plataform-integ-apps
    PASS: Platform-integ-app update to the new version with
    changed list of the charts
    PASS: Secrets no longer used were deleted
    PASS: If the update fails, it must remove the secrets that
    are in version N+1 and should not be in version N
