Will let the users know they can recover the tag via time machine
Note: This was tested with the Docker protocol, but the new error code is *technically* out of spec; we should make sure its okay.
this puts the view logic on the object and adds a parameter for logging

Makes the lookup query underneath the transaction smaller if there are a lot of images referenced directly by tag. We still must do the direct referenced check within the transaction, but this should reduce the scope of the search space a bit.
This prevents us from creating a massive join when there are a large number of tags in the repository, which can result in locking the entire DB for long periods of time. Instead of the join, we just iteratively lookup any images found to be directly referenced by a tag or found as a parent of another image, both of which should be indexed lookups. Once done, we only remove those images and then iterate until the working set stops changing.
before we would return a 400 without a message because the errors were not being caught

We remove the directly referenced images from the join across ancestors, as they will be covered by the first part of the union clause. For some large repositories, this will result in a significantly reduced set of images that have to be joined NxM.
there is a possibility that this will not work with postgres
