[Feature Request] Replace parts of image path to bypass docker registry cache

[Stitch10925]

Hey everyone,

I am currently using docker-registry-cache to cache images I am pulling so I don't have to re-download them, and to have a local version in case I would temporarily lose my internet connection.

The problem I am facing, is that none of the image version tracking tools work when a cache sits in-between.

When using Docker Registry Cache an Image path might look something like this:

localhost:5000/paperlessngx/paperless-ngx:2.12

Here the first part of the path is the url to the local cache, followed by the actual repository path.

I was wondering if a feature/configuration could be added in which you ask WUD to remove a certain text in the path. In my example removing "localhost:5000/" would yield the actual repository path without cache. When this path is used WUD could bypass the cache and check the version from the repository directly.

This would give me the best of both worlds: A cache and a way to check for version updates.
