removetags:2.1.5

The script will connect to specified Aqua console and retrieve all of the images. If the image has more than NUMBER_KEEP_TAGS number of tags, it will perform a sort on create_time field in the image tag data.

In cases where there is more than one tag with the same create_time field (eg, added simultaneously such as through 'Automatically pull images' setting in repository, or maybe 'Add all' selection in UI tag search), it will sort according to the tag's metadata field created, which is from date image is created.

Based on the number of images to keep, a sublist of images to delete will be generated. The script will then export the image data, and store it in a timestamped JSON file (except if it has not been scanned, then there is no output to save).

Then it will delete the image.
