Kazan v0.6.0

Breaking Changes

• The module names of most APIs & many models has been changed.
  • APIs module names have changed slightly to have a dot between the group name
    and the version. For example: Kazan.Apis.CoreV1 is now Kazan.Apis.Core.V1.
  • Models that are associated with an API now live inside that APIs module,
    rather than under Kazan.Models. For example Kazan.Models.Api.V1.Container
    now lives under Kazan.Apis.Core.V1.Container
  • Models that are not associated with specific APIs (e.g. Apimachinery models)
    still live under Kazan.Models. However, the capitalization of modules may
    have changed. For example ApiMachinery is now Apimachinery. This is
    mostly for consistencies sake - most module names only have the first letter
    capitalized, so Apimachinery etc. should be no different.
  • Some underlying changes in the names of models in the k8s spec may also have
    caused things to move around.
• It wasn't public API, but Kazan.Codegen.Models.property_name/1 has been
  removed.

New Features

• Updated Kubernetes specs to 1.8 (Thanks @chazsconi).
• Kazan can now load server details from kubeconfig provided in Mix configuration.
• Kazan can now be configured to use in cluster authentication from the Mix
  configuration.
• We now support watch requests with Kazan.Watcher. (Thanks @chazsconi)

Changes

• Switched CHANGELOG to use a format based on Keep a Changelog.
• Better documentation around how to authenticate with kubernetes.
• Changed the way "unknown" models are deserialized from k8s. We now try to
  match the apiVersion and kind fields with the data provided in the
  x-kubernetes-group-version-kind field in the OAI spec. If we're attempting
  to deserialize a model that doesn't hae this present in the spec, things may
  go wrong.
• Improved the documentation of API modules.

Deprecations

• Kazan.Models.oai_name_to_module still supports the older OAI name format,
  but this is now deprecated and will be removed in a future version.
• Kazan.Client has been deprecated in favor of exposing these functions in
  Kazan. See #23 for the justification.

Bug Fixes

• API functions that take no arguments will no longer raise
  Protocol.UndefinedError.
• read_namespaced_pod_log and other calls that return plain text will now
  return that text, rather than attempting & failing to decode JSON. (thanks
  @chazsconi)
• In cluster authentication using Kazan.Server.in_cluster should now work
  properly. It now reads the correct ca.crt file, and gets server details from
  environment variables, similar to the Go client. (Thanks @mayppong)
