"""
    When upgrading the prometheus operator we
    need to create CRDS each time. This script
    will automate the applying of those CRDS.
    If you are making a change to Prometheus
    Operator, and you get probeNamespaceSelector
    error, run this script and then execute
    the command that failed again and the
    error will be gone.
