Docker Registry v2.5.2

This release is a special security release to address an issue allowing
an attacker to force arbitrarily-sized memory allocations in a registry
instance through the manifest endpoint. The problem has been mitigated
by limiting the size of reads for image manifest content.

Details for mitigation are in 58d239d.

CVE-2017-11468 has been assigned for this issue.
