Device policy infrastructure

This continues the work of http://codereview.chromium.org/6312121/. Description of that CL:

This refactors the cloud policy-related code to support device policy
that gets associated with the whole browser session. Device policy
information will show up in g_browser_process->local_state(). Also,
start supporting recommended policy from the cloud.

BUG=chromium-os:11259, chromium-os:11257, chromium-os:11256
TEST=Enable device policy by passing --device-policy-cache-dir, claim a device and verify that policy gets downloaded.
