Simple callback that takes the node info from `/_cluster/nodes` and a
parsed connection information and return the connection information. If
`None` is returned this node will be skipped.
Useful for filtering nodes (by proximity for example) or if additional
information needs to be provided for the :class:`~elasticsearch.Connection`
class. By default master only nodes are filtered out since they shouldn't
typically be used for API operations.
:arg node_info: node information from `/_cluster/nodes`
:arg host: connection information (host, port) extracted from the node info
