Option to use *cider-result* popup-buffer

## Expected behavior
Display result of evaluation commands and debugging steps in ``*cider-result*`` popup-buffer just like ``cider--pprint-eval-form`` does.
- An option to pprint into ``*cider-result*`` when debugging and deactivate displaying result in an overlay.
- An option to pprint into ``*cider-result*`` when evaluating interactively and deactivate displaying result in an overlay.

## Actual behavior
Some commands use overlays, some use minibuffer.
Overlays can be deactivated but a pprint-popup-buffer can not be activated globally.

## Implementation
Looking for spots in the code suitable for such an option ...
