    [FAB-12576] failover while handling tx type B · f98f7c4e

    Raft cluster reconfigiration consists of two parts, first leader has to
    consent on configuration block, next leader has to extract new cluster
    configuration and propose raft configuration changes. However leader
    might fail between first and second parts, therefore newly selected
    leader should be able to detect there is unfinished reconfiguration and
    to finish reconfiguration.
    
    This commit adds logic to manage leadership failover, where new leader
    checks whenever last committed block is configuration block, whenever
    there are pending configuration changes and complete reconfiguration by
    proposing raft clust configuration changes.
