[Feature Request] Support Query Batching for Absinthe.Phoenix.Controller

[zimt28]

As discussed on Slack, Absinthe.Phoenix.Controller should support query batching. This allows, for example, running both a query and a mutation for one action, which is needed when a mutation fails (as changesets need the original data) or other information should be shown on the page.

Also, Absinthe.run should support the „special syntax“ and follow @action(mode: INTERNAL).

I just stumbled upon this - @action(mode: INTERNAL) from an Absinthe.run is exactly what I currently need! Anyone know if this is possible? Or if this feature request is a pipe-dream?
