> Make CAS retry logic configurable:
> One should be able to disable the internal CAS retry loop (when the condition is not
met) and let the client choose how to do retries (so the client does not have to incur the
server side random sleep of up to 100ms). Basically let the client handle all CAS retries
in a manor it sees fit.
> Secondly the hardcoded sleep up to 100ms that happens when cassandra fails to meet the
CAS condition should be configurable.
> - The max duration should be configurable
> - The algorithm used to choose the duration should be configurable (Random, Exponential,
etc).
