cc_ccache_iterator_release and cc_credentials_iterator leak memory on the 
CCacheServer because they do not send an ipc message to the server telling it
to free up resources associated with the iterator.

Note: this issue does not track needing to be able to free up these same 
resources when the client crashes.
