rbd: add target object existence flags
This creates two new flags for object requests to indicate what is
known about the existence of the object to which a request is to be
sent. The KNOWN flag will be true if the the EXISTS flag is
meaningful. That is:
KNOWN EXISTS
----- ------
0 0 don't know whether the object exists
0 1 (not used/invalid)
1 0 object is known to not exist
1 0 object is known to exist
This will be used in determining how to handle write requests for
data objects for layered rbd images.
