This PR adds a new field for paranoid durability to Ambry's Container class. The paranoid durability feature applies to PUTs/writes, and requires a minimum of one replica in a remote colo to acknowledge a write before returning success. We want this feature to be used sparingly, since it will add additional latency and cross-colo I/O to all writes. Therefore, the default setting for all containers is false (i.e. paranoid durability is OFF by default). So this new setting will need to be explicitly turned on for each container that wants to use it.
