This new method is used to return the state of the resource monitor for a deployment directly to a client. This helps with three major areas: 1) `Construct` and `Call` no longer need to be kept up to date with any new features added to `Run`. All they need is the resource monitor target and can use `GetState` to fetch all other information. 2) We no longer need to find a way to pass all the information from `Run` from the runtime host to the runtime SDKs. Instead all we need to pass is the (again) the resource monitor target, and on startup the SDK can fetch the rest of the information over gRPC. In fact we don't even need to add new information to `Run`, as the language runtime host can also just use `GetState` to fetch the latest information. 3) Features are now a safe enumeration lookup rather than a set of strings that could be typo'd. Further you don't need to make multiple roundtrips to see all features supported, the entire set is returned at once. A few things need pointing out about this change. Firstly SDKs that use this _also_ need to have a fallback to using the old envvar based approch because they might be running against an old engine version. Secondly this PR doesn't update any of the SDKs to use this. The most obvious candidate to update first is YAML as that doesn't actually have an SDK, just the host and the host _doesn't_ need to be backward compatible because we always tie host and engine versions together in a single release. |

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 Python version 3.7 or greater through official python installer
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.
Getting Started
The fastest way to get up and running is to choose from one of the following Getting Started guides: -aws -microsoft azure -google cloud -kubernetes
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.
