PolicyManager: UpdateCheckAllowed policy initial implementation.
This patch implements the UpdateCheckAllowed policy for ChromeOS
using the same logic we had on update_check_scheduler.cc. It checks
for updates onces every 45 minutes and does an exponential backoff
up to 4 hours when the update check fails. Some other parts of the
policy are not implemented, such as retry an update check with a
short delay on certain failures.
BUG=chromium:358269
TEST=Unittests added to the policy.
