Replace the internal microgrid API client with frequenz-client-microgrid (#892)

Unfortunately we can't remove the direct dependency on
`frequenz-api-microgrid` yet because some code is still using the raw
protobuf structures, as there are no wrappers for them yet (neither in
the internal code nor in `frequenz-client-microgrid`, which is based on
the SDK code).

Fixes #853.

 ## Upgrading
 
-<!-- Here goes notes on how to upgrade from previous versions, including deprecations and what they should be replaced with -->
+- The SDK is now using the microgrid API client from [`frequenz-client-microgrid`](https://github.com/frequenz-floss/frequenz-client-microgrid-python/). You should update your code if you are using the microgrid API client directly.
 
 ## New Features
 
 <!-- Here goes the main new features and examples or instructions on how to use them -->
 
 ## Bug Fixes
 
-<!-- Here goes notable bug fixes that are worth a special mention or explanation -->
+- A bug was fixed where the grid fuse was not created properly and would end up with a `max_current` with type `float` instead of `Current`.
