Bug description:
  starting with ONTAP 9.5 I get

  And indeed, the ONTAP API for cifs-domain-preferred-dc-add has a new
  required boolean option "skip-config-validation"

  [Impact]
  Using new releases of NetApp ONTAP (>= 9.5) leads to the following bug in the Manila code:
  https://bugs.launchpad.net/manila/+bug/1887643

  As Maurice Escher states, this results in the following error when
  creating a CIFS share with security service server set to some value:

  NetApp API failed. Reason - 13006:Missing input: skip-config-
  validation

  Only Ussuri distro packages are affected by this issue.

  This bug can be reproduced only when using `cifs` shares, and only
  when the driver handles shares servers.

  The issue was already fixed upstream, and it's even included in the
  latest Ussuri minor release: 10.0.2 (or even 10.0.1). Our Ubuntu
  distro packages install 10.0.0, and do not have this issue fixed.

  [Test Case]
  * Create an environment with Manila NetApp ONTAP driver and DHSS (driver handles shares enabled). This also requires an external Active Directory for the CIFS shares.
  * Create a new Manila CIFS share, given a proper Manila security service defined with the Active Directory info.
  * Bug is reproduced.

  [Where problems could occur]
  If the ontapi_version version was not calculated correctly the skip-config-validation config will result in the same error reported in this bug. Testing this code path will help mitigate this.
