Description

Support an async provides method for Fusion.js plugins. These should be resolved prior to being passed in as dependencies to other plugins.

Current behavior

createPlugin({
   deps: {},
   provides: async (deps) => {
      const service: SomeLibraryType = new SomeLibrary();
      await service.init();
      return service;
   }
});

If the above plugin were used as a dependency, it would resolve to Promise<SomeLibraryType>.

Expected behavior

Ideally consumers can use the underlying library directly, and dependents would have access to the underlying service:

createPlugin({
   deps: { someLibrary: SomeLibraryToken },
   provides: (deps) => {
      const someLibrary: SomeLibraryType = deps.someLibrary; // not a Promise
   }
}
