Redundancy with Dynamic Resource Providers

[dga-nagra]

Hi,

I am trying to follow Dynamic resource providers.
I want to define 1 provider that knows the credentials, and multiple resources for this provider.

The current way forces me to create 1 Provider per resource:

class NetmikoUsernameProvider(ResourceProvider):
    def create(...):
        ...
class NetmikoUsernameResource(Resource):
    ...
class NetmikoAAAProvider(ResourceProvider):
    def create(...):
        ...
class NetmikoAAAResource(Resource):
    ...

When I expected something like:

class NetmikoProvider(ResourceProvider):
    ...
class NetmikoUsernameResource(Resource):
    def create(...):
        ...
class NetmikoAAAResource(Resource):
    def create(...):
        ...

We can also not use the opts=pulumi.ResourceOptions(provider=myprovider) method to select the provider (it misses the "package" attribute) and we are required to give the provider in the __init__ of the resource. Hopefully I can add a provider parameter to it.

This is not so much of a burden when we can hardcode the provider instantiation in the resource, but when we have multiple resources for multiple providers, this becomes a real pain.

I am wondering why this was made this way and how I could re-use a single provider definition? Can someone explain this and/or provide an alternative to this ?
I see there are some serialization with pickle, so I cannot even send callbacks (or not easily).
