    Fix certificate ssl_ca cert install by dc-orch sync

    This commit fixes an issue where the subcloud's kubernetes root CA
    is installed as a ssl_ca in the subcloud. This is not needed and will
    result in an 'Cannot install certificate with same subject' error when
    dc-orch tries to synchronize it's kubernetes root CA as a ssl_ca
    certificate to the subcloud.

    Test Plan:

    PASS: Run dcmanager subcloud add and verify that no ssl_ca certificates
          with subject 'CN=starlingx' exists in 'system certificate-list'
    PASS: Bootstrap a standalone system and verify that a ssl_ca certificate
          with subject 'CN=starlingx' exists in 'system certificate-list'
    PASS: Manage a subcloud and verify that it's able to synchronize certs
          without the 'Cannot install certificate with same subject' error
