Breaking changes

- Support for Python 3.3 and Python 3.4 has been dropped
- `APIClient.update_service`, `APIClient.init_swarm`, and
`DockerClient.swarm.init` now return a `dict` from the API's response body
- In `APIClient.build` and `DockerClient.images.build`, the `use_config_proxy`
parameter now defaults to True
- `init_path` is no longer a valid parameter for `HostConfig`

Features

- It is now possible to provide `SCTP` ports for port mappings
- `ContainerSpec`s now support the `init` parameter
- `DockerClient.swarm.init` and `APIClient.init_swarm` now support the
`data_path_addr` parameter
- `APIClient.update_swarm` and `DockerClient.swarm.update` now support the
`rotate_manager_unlock_key` parameter
- `APIClient.update_service` returns the API's response body as a `dict`
- `APIClient.init_swarm`, and `DockerClient.swarm.init` now return the API's
response body as a `dict`

Bugfixes

- Fixed `PlacementPreference` instances to produce a valid API type
- Fixed a bug where not setting a value for `buildargs` in `build` could cause
the library to attempt accessing attributes of a `None` value
- Fixed a bug where setting the `volume_driver` parameter in
`DockerClient.containers.create` would result in an error
- `APIClient.inspect_distribution` now correctly sets the authentication
headers on the request, allowing it to be used with private repositories
This change also applies to `DockerClient.get_registry_data`
