> When a node joins a cluster it needs to send and receive some discovery metadata, for example:
>  # A node might need to provide some credentials and/or some of its configuration values in order to be validated against the state of the cluster.
>  # A node might need to obtain some information about the cluster when accepted into the topology, e.g. addresses of the nodes that host the metastorage.
> We should develop a mechanism for both sending and receiving some data before a node is accepted into the topology. As a proof of concept it will be enough to receive information about the nodes hosting the metastorage.
