Add a system property (dse.consistency_level.three_means_all_but_one) that changes the behavior of ConsistencyLevel.THREE to mean ALL_BUT_ONE, i.e. that all replicas except for at most one in the cluster (across all DCs) must accept the write for it to be successful.

Some context for why it's needed
This patch was originally implemented in DSE under DSP-22366, the goal of this PR is to port it to CC to ensure DSE7 remains backwards compatible with 5.1 and 6.8.
This PR was created as a supplement of #936 to prevent code divergence.
