Add storeGroups/restoreGroups method to LED Manager

Use CEREAL to storeGroup/restoreGroups the current state of
asserted groups.
Call storeGroups() when the request comes to add to(remove from)
asserted group.
Call restoreGroups() as part of starting LED Manager daemon.

Tested: Manually set the Asserted property of each group to true,
after rebooting, all property values tested with the busctl command
are still true.
