Removal of a Toolbox image from which are derived Toolbox containers made a one-step operation

**Problem description**

Hello. Removal of a _Toolbox_ image from which are derived _Toolbox_ containers is a two-step operation.

'`toolbox rm && toolbox rmi `'

Attempt as a one-step operation
```
$ toolbox rmi
Error: image has dependent children
```
_goal_: Avoiding the unnecessary print of an error message by offering the possibility to make the removal a one-step operation.

**Solution description**

Removal of a _Toolbox_ image from which are derived _Toolbox_ containers made a one-step operation.

Suggested interactive output:
```
$ toolbox rmi
Image has dependent children that must be removed first in order to remove the image.
##IDs of containers derived from the image:##
####
Do you want to remove these containers? [N/y]:
```
**Alternatives I have considered**
Such removal in Podman is a two-step operation as well. I wish it was an alternative.

Start at the implementation of the `toolbox rmi` command and compare it with the existing `toolbox rm` behavior. Trace how dependent containers are identified and how the current error is reported. Done means `toolbox rmi` can offer interactive removal of the listed dependent containers before removing the image.
