CM should support majority-vote failover arbitration as an alternative to priority-based

See this idea on ideas.ibm.com

Currently, the Informix Connection Manager handles failover arbitration on the basis of a priority setting in the ${CMCONFIG} file. This has the effect of making a single CM the judge, jury and executioner when it comes to failover events. And it can be problematic in cases where, for example, the CMs are distributed across multiple data centers and the wrong CM loses contact with the primary database server. In a worst case, it can lead to a "split brain" scenario.


Other DB products (e.g., MongoDB, Galera Cluster) instead used a majority-wins strategy in handling failover, and this alleviates the above problems. Before automatic failover is initiated, a majority of CMs must agree that the primary is down/inaccessible.
