[jira] [Updated] (IGNITE-14870) Define a mechanism for exchanging discovery metadata

["Sergey Chugunov (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/IGNITE-14870?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Sergey Chugunov updated IGNITE-14870:
-------------------------------------
    Description: 
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.

As part of the task an IEP-77 was prepared, linked to the ticket below.
