Python dynamic providers get serialised and deserialised, and run in the
`pulumi-python` plugin process. This causes issues when trying to use
`pulumi.config.Config` in a dynamic provider:
* Using `Config` at runtime fails because the process is not setup with
the current configuration
* When the dynamic provider implementation is in the `__main__` module,
the dynamic provider serialization attempts to serialize the global
`SETTINGS` object, which pulls in protobuf definitions, which are not
serializable by `dill`.
To provide a stable API to access configuration in dynamic providers,
the provider classes (ResourceProvider) can now implement a `configure`
method which is called during provider initialization.
```python
class SimpleProvider(ResourceProvider):
password: str
def configure(self, req: ConfigureRequest):
self.password = req.config.get("password")
def create(self, props):
# Use `self.password`.
...
```
The `configure` method is called when a provider is deserialized. Since
we cache the deserialization result, we guarantee that this is only
called once per program, and this process level cache serves as a plugin
registry.
