* [docker_network] Fix idempotency when using aux_addresses in ipam_config
Mismatch between keys returned by Docker API (AuxilliaryAddresses) vs
expected by Ansible module (aux_addresses) resulted in tasks always
have status 'changed'. The existing code normalizing one set of
keys to another missed this special case where converting
CamelCase to lowercase is not sufficent.
Please see

for reference.
* Correct keywords formatting in changelog file
