Rework error/status reporting for resources

[ash2k]

Currently some things that aren't error are propagated as if they are within the code. For example, if an object, described in a bundle, exists but is marked for deletion that is reported as a terminal error in the resource's status. This is not an error, this should be reflected as "in progress" situation. There are more things like that. In general, more things should be propagated as just information about a resource, not as an error return value. Error return values should be used for true errors like unexpected failures, I/O failures, so on.
