Implementation is done on top of feature/is-healthiest-via-api and feature/api branches. In order to trigger manual failover one has to create 'failover' key in a configuration store with the value in following format: 'leader_name:member_name' leader_name can be empty or should match with the name of current leader member_name can be empty or should match with the name one of cluster nodes Leader always checks that either desired member (if specified) or one of the memners is accessible and healthy before demote. After leader has deomted himself other nodes are performig checks that desired node is healthy. If it is not they are participating in a leader race. In some cases (when accidently there is no healthy nodes) former leader can also participate in a leader race. Current implementation does not provide REST API endpoint for a manual failover.
