update_engine: Add Update Time Restrictions
Implementation for the update time restrictions policy where the admin
is allowed to choose time interval in which updates will not be checked.
- Adds WeeklyTime and WeeklyTimeInterval classes to update_engine to be
able to easily do interval range checking and time operations easily in
the policy. Added the wiring so the classes can be used as Values and
BoxedValues.
- Adds disallowed_intervals member to device_policy_provider, since this
contains the policy dictated disallowed intervals. The intervals are
obtained from libpolicy, a function was added to convert them to the
new WeeklyTime classes. Added the corresponding changes to the device
policy provider header and interface.
- Added the policy to chromeos_policy.cc so that it's taken into account
in UpdateCheckAllowed.
