Parameterization refers to the ability for a provider to vary its schema based on a parameter that is passed to a new `Parameterize` call on the provider interface. The package reference that is returned may then be used to interact with the bespoke schema/packages within. Paramterization is key to e.g. dynamically bridging providers. In this instance we can manage and release a single "bridge" provider that accepts a parameter defining the upstream provider to bridge, and returns a reference to a dynamically constructed package whose schema reflects the upstream as needed. This commit adds support for calling parameterized `Invoke`s from the Python SDK. As with resources, the `get_package()` utility function is used to retrieve the parameter we bake into the SDK, before passing this to the engine. |

Pulumi Python SDK
The Pulumi Python SDK (pulumi) is the core package used when writing Pulumi programs in Python. It contains everything that you’ll need in order to interact with Pulumi resource providers and express infrastructure using Python code. Pulumi resource providers all depend on this library and express their resources in terms of the types defined in this module.
The Pulumi Python SDK requires a supported version of Python.
note: pip is required to install dependencies. If you installed Python from source, with an installer from python.org, or via Homebrew you should already have pip. If Python is installed using your OS package manager, you may have to install pip separately, see Installing pip/setuptools/wheel with Linux Package Managers. For example, on Debian/Ubuntu you must run sudo apt install python3-venv python3-pip.

Pulumi Programming Model
The Pulumi programming model defines the core concepts you will use when creating infrastructure as code programs using Pulumi. Architecture & Concepts describes these concepts with examples available in Python. These concepts are made available to you in the Pulumi SDK.
The Pulumi SDK is available to Python developers as a Pip package distributed on PyPI . To learn more, refer to the Pulumi SDK Reference Guide.
The Pulumi programming model includes a core concept of Input and Output values, which are used to track how outputs of one resource flow in as inputs to another resource. This concept is important to understand when getting started with Python and Pulumi, and the [Inputs and Outputs] (https://www.pulumi.com/docs/intro/concepts/inputs-outputs/)documentation is recommended to get a feel for how to work with this core part of Pulumi in common cases.
The Pulumi Python Resource Model
Like most languages usable with Pulumi, Pulumi represents cloud resources as classes and Python programs can instantiate those classes. All classes that can be instantiated to produce actual resources derive from the pulumi.Resource class.
