With the addition of [a], the minimum openstacksdk version needs to
be bumped to include [b], or the os_network module will return the
error:
TypeError: create_network() got an unexpected keyword argument 'dns_domain'
To handle this, we fail the module if the dns_domain argument is used
and the minimum openstacksdk version for that argument is not met.
