    ZOOKEEPER-2819:Changing membership configuration via rolling restart …

    …does not work on 3.5.x.
    
    This patch disables the creation of dynamic config files (zoo.cfg.dynamic) and static
config back up files (zoo.cfg.bak) when the dynamic reconfig feature flag (reconfigEnabled)
is disabled. With this patch the membership information (such as server list) will be stored
in static zoo.cfg file and such information would not go through quorum and leader / follower
sync phase, which makes it possible for users to continue using the old rolling restart approach.
    
    @shralex PTAL.
