Add force, noprune option to PurgeImages GQL API

[jopemachine]

Motivation  

When the administrator runs "purge images," there may be cases where certain options need to be used.

Required Features

The purge images CLI command and GQL arguments will include the force and noprune options.

Impact  

The administrator will be able to modify these options when running the purge images command.

Testing Scenarios  

For example, when calling purge images on an image that is currently in use, an error occurs because the default value of the force option is False, preventing the image from being deleted.

Check that when the force option is set to True, the error does not occur and the in-use image is deleted immediately.
