Description

With atomic slot migration (#1949) we need to establish links across shards for the purpose of migrating slot content.

The existing MIGRATE commands supports AUTH2 username password or AUTH password. Similar options could be supported via the CLUSTER MIGRATESLOTS command (which now will default to the primary authentication settings, if set)

Contributor guide

Research direction
Study the existing MIGRATE command's AUTH and AUTH2 implementation to understand the pattern, then apply it to CLUSTER MIGRATESLOTS command handler.
