      Apply @param updates if and only if the current values in the row for @param key match the provided @param conditions. The algorithm is "raw" Paxos: that is, Paxos minus leader election -- any node in the cluster may propose changes for any row, which (that is, the row) is the unit of values being proposed, not single columns. The Paxos cohort is only the replicas for the given key, not the entire cluster. So we expect performance to be reasonable, but CAS is still intended to be used "when you really need it," not for all your updates. There are three phases to Paxos: 1. Prepare: the coordinator generates a ballot (timeUUID in our case) and asks replicas to (a) promise not to accept updates from older ballots and (b) tell us about the most recent update it has already accepted. 2. Accept: if a majority of replicas reply, the coordinator asks replicas to accept the value of the highest proposal ballot it heard about, or a new value if no in-progress proposals were reported. 3. Commit (Learn): if a majority of replicas acknowledge the accept request, we can commit the new value. Commit procedure is not covered in "Paxos Made Simple," and only briefly mentioned in "Paxos Made Live," so here is our approach: 3a. The coordinator sends a commit message to all replicas with the ballot and value. 3b. Because of 1-2, this will be the highest-seen commit ballot. The replicas will note that, and send it with subsequent promise replies. This allows us to discard acceptance records for successfully committed replicas, without allowing incomplete proposals to commit erroneously later on. Note that since we are performing a CAS rather than a simple update, we perform a read (of committed values) between the prepare and accept phases. This gives us a slightly longer window for another coordinator to come along and trump our own promise with a newer one but is otherwise safe.
      Parameters:
        `keyspaceName` - the keyspace for the CAS
        `cfName` - the column family for the CAS
        `key` - the row key for the row to CAS
        `request` - the conditions for the CAS to apply as well as the update to perform if the conditions hold.
        `consistencyForPaxos` - the consistency for the paxos prepare and propose round. This can only be either SERIAL or LOCAL_SERIAL.
        `consistencyForCommit` - the consistency for write done during the commit phase. This can be anything, except SERIAL or LOCAL_SERIAL.
      Returns:
        null if the operation succeeds in updating the row, or the current values corresponding to conditions. (since, if the CAS doesn't succeed, it means the current value do not match the conditions).
      Throws:
        `UnavailableException`
        `IsBootstrappingException`
        `ReadTimeoutException`
        `WriteTimeoutException`

      Handle counter mutation on the coordinator host. A counter mutation needs to first be applied to a replica (that we'll call the leader for the mutation) before being replicated to the other endpoint. To achieve so, there is two case: 1) the coordinator host is a replica: we proceed to applying the update locally and replicate throug applyCounterMutationOnCoordinator 2) the coordinator is not a replica: we forward the (counter)mutation to a chosen replica (that will proceed through applyCounterMutationOnLeader upon receive) and wait for its acknowledgment. Implementation note: We check if we can fulfill the CL on the coordinator host even if he is not a replica to allow quicker response and because the WriteResponseHandlers don't make it easy to send back an error. We also always gather the write latencies at the coordinator node to make gathering point similar to the case of standard writes.

        `UnavailableException`
