Security update for docker (important)

docker was updated to version 1.8.3 to fix two security issues.

These security issues were fixed:

• CVE-2014-8178: Manipulated layer IDs could have lead to local graph
  poisoning (bsc#949660).
• CVE-2014-8179: Manifest validation and parsing logic errors allowed
  pull-by-digest validation bypass (bsc#949660).

This non-security issues was fixed:

• Add --disable-legacy-registry to prevent a daemon from using a v1
  registry
