Remove dynamic-address-fact call which is no longer required

I don't believe this is necessary anymore since 'management_ip'
was introduced into openstack_user_config.

Whether 'management_ip' is set or not, 'management_address' is
already set in the inventory, and if dynamic-address-fact runs
here it can confusingly override the value of 'management_address'.
