UpdateEngine-side changes to allow updates over 3G based on device policy.
Some enterprise chromebooks have only 3G and hence they need the ability
to update over 3G if the enterprise policy allows that. This CL adds
the support in update_engine to enable that.
BUG=chromium-os:31099
TEST=Tested E2E on 3G, added unit tests and did regression testing.
