Storage plugin

[gcolombeau]

Hello, I saw that there is an open discussion for a future plugin mechanism for prefect-server though I'm not sure if this particular topic belongs to it or not.
I was trying to write a small plugin for a Bitbucket Cloud storage by simply inheriting the Bitbucket storage and adapt the client method to configure it with a username and app password (thanks Atlassian for this...).
Unfortunately, using a local agent (not sure if other agents have the exact same mechanism) you can load the plugin and manually start the agent but it is not possible to register the associated storage schema in a way that is picked up by a flow run because it is launched by calling the CLI in a sub-process.
So, is there already some plan to add a mechanism (via entry points or else) to be able to register plugins for new storage classes?
