Add new optional parameter for ConfigEntries.async_entries to specify whether or not ignored entries should be included

[raman325]

Proposed change

In fixing an issue with the vizio integration I thought it would be nice if the async_entries function could return only non-ignored config entries so that other integrations do not have to build custom logic like vizio has. This change adds an optional additional parameter to the function that will optionally filter ignored config entries out. The default is set to make this change backwards compatible.

I don't think that it's a good idea. We shouldn't ignore ignored entries in our checks if things are already set up .

It's useful for my case where I am iterating through config entries to check for the existence of keys that wouldn't exist on an ignored entry, but I can close this if you don't think this is a problem for other integration

Let's not add it to the main object.
