anchor.diff:      handshake. Defaults to `1s`.
   
   `discovery.request_peers_timeout`::
  +
       Sets how long a node will wait after asking its peers again before
       considering the request to have failed. Defaults to `3s`.
   
  
positive.code: 
      Sets the amount to increase the upper bound on the wait before an election
      on each election failure. Note that this is _linear_ backoff. This defaults
      to `100ms`
  
  `cluster.election.duration`::
  
      Sets how long each election is allowed to take before a node considers it to
      have failed and schedules a retry. This defaults to `500ms`.
  
  `cluster.election.initial_timeout`::
  
      Sets the upper bound on how long a node will wait initially, or after the
      elected master fails, before attempting its first election. This defaults
      to `100ms`.
  
  
  `cluster.election.max_timeout`::
  
      Sets the maximum upper bound on how long a node will wait before attempting
      an first election, so that an network partition that lasts for a long time
      does not result in excessively sparse elections. This defaults to `10s`
  
  [[fault-detection-settings]]`cluster.fault_detection.follower_check.interval`::
  
      Sets how long the elected master waits between follower checks to each
      other node in the cluster. Defaults to `1s`.
  
  `cluster.fault_detection.follower_check.timeout`::
  
      Sets how long the elected master waits for a response to a follower check
      before considering it to have failed. Defaults to `10s`.
  
  `cluster.fault_detection.follower_check.retry_count`::
  
      Sets how many consecutive follower check failures must occur to each node
      before the elected master considers that node to be faulty and removes it
      from the cluster. Defaults to `3`.
  
  `cluster.fault_detection.leader_check.interval`::
  
      Sets how long each node waits between checks of the elected master.
      Defaults to `1s`.
  
  `cluster.fault_detection.leader_check.timeout`::
  
      Sets how long each node waits for a response to a leader check from the
      elected master before considering it to have failed. Defaults to `10s`.
  
  `cluster.fault_detection.leader_check.retry_count`::
  
      Sets how many consecutive leader check failures must occur before a node
      considers the elected master to be faulty and attempts to find or elect a
      new master. Defaults to `3`.
  
  `cluster.follower_lag.timeout`::
  
      Sets how long the master node waits to receive acknowledgements for cluster
      state updates from lagging nodes. The default value is `90s`. If a node does
      not successfully apply the cluster state update within this period of time,
      it is considered to have failed and is removed from the cluster. See
      <<cluster-state-publishing>>.
  
  `cluster.initial_master_nodes`::
  
      Sets a list of the <<node.name,node names>> or transport addresses of the
      initial set of master-eligible nodes in a brand-new cluster. By default
      this list is empty, meaning that this node expects to join a cluster that
      has already been bootstrapped. See <<initial_master_nodes>>.
  
  `cluster.join.timeout`::
  
  
negative.code:     to use to obtain the addresses of the seed nodes used to start the
      discovery process. By default, it is the
      <<settings-based-hosts-provider,settings-based seed hosts provider>>.
  
  `cluster.initial_master_nodes`::
  
      Sets a list of the <<node.name,node names>> or transport addresses of the
      initial set of master-eligible nodes in a brand-new cluster. By default
      this list is empty, meaning that this node expects to join a cluster that
      has already been bootstrapped. See <<initial_master_nodes>>.

  ==== Expert settings
  
  Discovery and cluster formation are also affected by the following
  _expert-level_ settings, although it is not recommended to change any of these
  from their default values.
  
  [WARNING] If you adjust these settings then your cluster may not form correctly
  or may become unstable or intolerant of certain failures.
