Shouldn't something like docker pull 10.192.203.193/redis:4.0 work now?

Building harbor from source and testing this PR results in an error: Error response from daemon: unknown: bad request: invalid repository name: redis

core.log logs an ERROR message containing: authutils.go:104]: Failed to handle the resource repository:redis, due to error unable to parse image from string: redis, returning empty access for it.

This error looks like it can be traced back to parseImg in creator.go, which can't account for this new acceptable pull format that this PR should enable.
