Add an api to get and set a gc blacklist, to schedule nodes for removal from DDFS.
The gc blacklist differs from a write blacklist in the following
sense: a node
on the write_blacklist will not have new DDFS data being written to
it, but any
existing data is treated as stable. A node on the gc blacklist is
treated as
unstable; additional replicas are generated for any data and
metadata on that
node.
