[Feat request] Purge entity

[enfJoao]

I'm submitting a ...
[x] feature request

...about
[x] admin experience UI

Current behavior
There is no way to quick delete all entries in an entity (perhaps with some complex export->import)

Expected behavior
A button could be created for each entity (in the right block of buttons) to purge an entity (perhaps hidden from normal use and shown only in debug mode).

What is the motivation / use case for changing the behavior?
When developing a new app, the entities that receive the data from forms will fill with quite a few dozens of test entries. Deleting one at a time is quite slow.

At the moment you'll have to use export/re-import, as such a feature won't be implemented in the near future. So i'll close this for now.
