------------------------------------------

We should also put such restriction for CAS operations.

> A C* instance will serve CF level reads with null values or old values to a co-ordinator
even if the instance is not responsible for the data. 
> This is bad if co-ordinator has a wrong view of the ring and will return wrong results
back to the client. 
> A solution to this problem could be to not respond or return error to such read requests.

> Tricky part here is to respond to read requests when the instance has just lost ownership
for a few ring delay.
