New policy protobuf protocol.

(Third attempt to land http://codereview.chromium.org/6409040/ -- now without memory leaks)

- cloud_policy.proto autogenerated from policy_templates.json
- C++ method decoding the protobuf also autogenerated from policy_templates.json
- changed policy fetching mechanism to fetch new-style policy protobufs

BUG=68309, chromium-os:11253, chromium-os:11255
TEST=CloudPolicyCacheTest.*; also manual test against python testserver
