Describe your feature request

It is already possible to give actors a name: https://docs.ray.io/en/master/actors.html#named-actors and to retrieve the actor handle via ray.get_actor("some_name").
It would however be very handy to have some kind of ray.list_named_actors() API method to get a list/dict of all currently available named actors.
It can be useful for:

• Better debugging

I'm sorry if I missed this functionality, but CLI version hasn't it for sure (I saw the related code only in generate_code_examples.py). I guess it will be very useful to eliminate copy-paste phase, especially for large models.

Of course, piping is a solution, but not for development in Jupyter Notebook, for example.

We noticed that we have some common patterns for common conflicts/duplicate resolution in our monorepo across different binaries.
Like

  deploy_jar_rules=jar_rules(rules=[
    Duplicate('^BUILD', Duplicate.SKIP),
    Duplicate('^META-INF/ASL2.0', Duplicate.SKIP),
    Duplicate('^META-INF/INDEX.LIST', Duplicate.SKIP),
    Duplicate('^META-INF/io.netty.versions.properties', Duplicate.SKIP
