Feature Request: Investigate adding async support for components

[dlabaj]

Many applications are using a form of async communication (promises, observables, etc.) to load components. It would nice to have an optional feature that would provide this support for some of our components (e.g. A function that sets a state to loading, call an async function, and then load the component according to the developers needs) to do this in a standardize way.

Here is an example on how it's done with react-select:

https://react-select.com/async

If we can find a way to do this across components using the same API, and same code that would be the ideal solution.

This would be in addition to the demo request in #3405

In case it is helpful, we have a simple solution I cobbled together for the seed project to facilitate this. It does the job technically but has some issues. Here's how you define a component using it. Probably better ways of accomplishing this, just wanted to +1 the idea and show what we have. I would love to use something PF supported instead, and happy to help test/review the solution when it's ready.

Note for posterity: The solution @seanforyou23 is referring to above was removed from the patternfly-react-seed repo in patternfly/patternfly-react-seed#103. @seanforyou23's links above no longer work since they referenced the main branch: here's a permalink to the DynamicImport.tsx file before it was deleted, and a permalink to the usage before it was removed.

It seems that solution was causing issues during a dependency upgrade and was removed since it was just a stub. If this is ever revisited, restoring that may be a good starting point.

The rabbit hole that got me here is described in this comment: patternfly/patternfly-react-seed#103 (comment)
