Severity
--------
Minor: System/Feature is usable with minor issue

Steps to Reproduce
------------------
1) Take the master branch code of app-security-profiles-operator repo{}
2) system application-upload security-profiles-operator-1.0-1.tgz
3) check /var/log/sysinv.log

    Improvement log error indicating namespace not found

    Namespace not found error message is shown in sysinv.log when an application that has a specific namespace is uploaded.

    This log is expected and has no impact on the system. This
    happens due to the command "kubectl -k <manifest_dir>
    --dry-run=server". If the application has a specific namespace that
    the system does not yet have, the command shows this error. But
    there is nothing to worry about, as the namespace is created within
    the apply process.

    To avoid misinterpretations, this log has been suppressed.

    Test Plan:
    PASS: Add the new log to kube_app.py and restart sysinv.
    PASS: During the application upload process, the log that says the
          namespace was not found no longer appears.

    Closes-Bug: 2067070
