        :param node_id: The node identifier. This parameter is not validated against
            the cluster's active nodes. This enables you to register a node for shut
            down while it is offline. No error is thrown if you specify an invalid node
            ID.
        :param reason: A human-readable reason that the node is being shut down. This
            field provides information for other cluster operators; it does not affect
            the shut down process.
        :param type: Valid values are restart, remove, or replace. Use restart when you
            need to temporarily shut down a node to perform an upgrade, make configuration
            changes, or perform other maintenance. Because the node is expected to rejoin
            the cluster, data is not migrated off of the node. Use remove when you need
            to permanently remove a node from the cluster. The node is not marked ready
            for shutdown until data is migrated off of the node Use replace to do a 1:1
            replacement of a node with another node. Certain allocation decisions will
            be ignored (such as disk watermarks) in the interest of true replacement
            of the source node with the target node. During a replace-type shutdown,
            rollover and index creation may result in unassigned shards, and shrink may
            fail until the replacement is complete.
        :param allocation_delay: Only valid if type is restart. Controls how long Elasticsearch
            will wait for the node to restart and join the cluster before reassigning
            its shards to other nodes. This works the same as delaying allocation with
            the index.unassigned.node_left.delayed_timeout setting. If you specify both
            a restart allocation delay and an index-level allocation delay, the longer
            of the two is used.
        :param master_timeout: The period to wait for a connection to the master node.
            If no response is received before the timeout expires, the request fails
            and returns an error.
        :param target_node_name: Only valid if type is replace. Specifies the name of
            the node that is replacing the node being shut down. Shards from the shut
            down node are only allowed to be allocated to the target node, and no other
            data will be allocated to the target node. During relocation of data certain
            allocation rules are ignored, such as disk watermarks or user attribute filtering
            rules.
        :param timeout: The period to wait for a response. If no response is received
            before the timeout expires, the request fails and returns an error.
