Aaron Lehmann e87491eb72 Avoid redundant HEAD requests for identical layers on push ...

pushV2Tag already deduplicates layers, but the scope of this
deduplication is only for a particular tag. If we are pushing all tags
in a repository, we may check layers several times. Fix this by moving
the layersSeen map from the pushV2Tag function to the v2Pusher struct.

In addition to avoiding some useless round-trips, this makes the "docker
push" output less confusing. It formerly could contain many repeated
lines like:

    124e2127157f: Image already exists
    124e2127157f: Image already exists
    ...

Add test coverage based on the "docker push" output: a hash should not
appear multiple times when pushing multiple tags.

Fixes #14873
