Make it intuitive and seamless for MONAI to be extended to FL. Focus on client side integrations first.
Create components to allow running MONAI pipelines in any FL framework.

Suggesting to create a new folder (i.e., monai/fl) containing the following subfolders and objects:

client:
ClientAlgo base class
MONAIAlgo reference implementation that can parse MONAI bundle configuration files
utils:
ExchangeObject, Filters and other helper/utility classes.
