availability zones configuration could not be applied: request failed: unexpected response

[ceesco53]

Describe the bug

There is a bug within configure-director task and director.yml configuration file generated by om command om staged-director-config.

A section named az-configuration is present within director.yml to configure Availability Sets. When used to create a foundation configure-director task and director.yml config file works fine, but when used to modify director config after that it has been created failed with this error message.

Reproduction steps

...

Expected behavior

The error is not supposed to happen since first we don't try to modify anything on Availability Sets and second because it's included into the configuration file generated by om command om staged-director-config.

Additional context

The workaround is to comment the specific az-configuration section present within director.yml

az-configuration:
name: Availability Sets
iaas_configuration_name: default
guid: 18ba5004b62a5b36835d
iaas_identifier: null
