Improve the way we declare and use (optional) collector fields Entity and Monitor objects were updated to work with optional fields better. Both were also updated to throw an error when an access to non-declared field is attempted. It is now also possible to specify default value for field in Entity.Stat to make the optional fields more usable in the policy. Guest Memory collector field declaration was changed to explicitly state the collected fields. This should reduce the confusion in what fields are supposed to be collected in libvirt vs. in vdsm environment. It is my opinion that the field declaration is part of the collector's metadata and should be explicitly specified rather than inferred. New Guest Memory collector (GuestMemoryOptional) that treats all fields as optional is added as an example. It also helps when a policy should support more than ballooning and is supposed to work (with ballooning ignored) even when no guest agent is available and internal memory stats are missing. This should keep us compatible with vdsm who has GuestMemory in mom.conf and give us the option to use the new collector with updated ballooning policy in the future vdsm releases.
