[Enhancement] Multi close toast notifications

[philippkahr]

Hi,

sometimes you run into such issues, displaying a lot of toast notifications. (especially when using async searches, since TSVB, timelion do not work with it)

You can now just reload the entire page, which takes time and kicks off the same search again (since you cannot change the search, because the toasts are in the way :D). From a user experience perspective, I do not find that this is the best possible solution.

I can think of two improvements:

1. there should be some close all toasts button somewhere.
2. Stack toasts notifications and add close all something like this:

When stacking we could go even further a stack similar errors into a stack. E.g. essagg error vs timeline error toasts.

Kibana Version: 7.8.0

I honestly consider this to be a Kibana issue and not EUI. Kibana should consider not duplicating the same error messages and/or grouping all similar errors into one toast. I'm going to move this issue to the Kibana repo.
