-### Types and Providers
-
-#### Aviator
-
-#####`Puppet::add_aviator_params`
-
-The aviator type is not a real type, but it serves to simulate a mixin model,
-whereby other types can call out to the Puppet::add\_aviator\_params method in
-order to add aviator-specific parameters to themselves. Currently this adds the
-auth parameter to the given type. The method must be called after the type is
-declared, e.g.:
-
-```puppet
-require 'puppet/type/aviator'
-Puppet::Type.newtype(:my_type) do
-# ...
-end
-Puppet::add_aviator_params(:my_type)
-```
-
-#####`Puppet::Provider::Aviator`
-
-The aviator provider is a parent provider intended to serve as a base for other
-providers that need to authenticate against keystone in order to accomplish a
-task.
-
-**`Puppet::Provider::Aviator#authenticate`**
-
-Either creates an authenticated session or sets up an unauthenticated session
-with instance variables initialized with a token to inject into the next request.
-It takes as arguments a set of authentication parameters as a hash and a path
-to a log file. Puppet::Provider::Aviator#authencate looks for five different
-possible methods of authenticating, in the following order:
-
-1) Username and password credentials in the auth parameters
-2) The path to an openrc file containing credentials to read in the auth
-   parameters
-3) A service token in the auth parameters
-4) Environment variables set for the environment in which Puppet is running
-5) A service token in /etc/keystone/keystone.conf. This option provides
-   backwards compatibility with earlier keystone providers.
-
-If the provider has password credentials, it can create an authenticated
-session. If it only has a service token, it initializes an unauthenciated
-session and a hash of session data that can be injected into a future request.
-
-**`Puppet::Provider::Aviator#make_request`**
-
-After creating a session, the make\_request method provides an interface that
-providers can use to make requests without worrying about whether they have an
-authenticated or unauthenticated session. It takes as arguments the
-Aviator::Service it is making a request at (for example, keystone), a symbol for
-the request (for example, :list\_tenants), and optionally a block to execute
-that will set parameters for an update request.
