#3763 [HHQ-3263] Add APIs for down resources

[Hyperic Team]

http://jira.hyperic.com/browse/HHQ-3263


Initial thought is to add these to ResourceApi:

public ResourcesResponse getDownResources()


public ResourcesResponse getDownResources(ResourcePrototype pt)


public ResourcesResponse getDownResources(Group g)

These APIs would return only the list of Resources.

Another alternative would be to create a new DownResource object that would include the Resource itself and how long it's been down.
