couchbase-cli server-add requires --username instead of --user

While upgrading from 6.0.x to 6.5.1, it was found that our script to add a server back to the cluster was not working correctly. Upon further investigation it was found that the script was using couchbase-cli server-add command with --user as an option to provide the username. Somehow it looks as though this was changed to --username in 6.5.x. However the documentation still states to use --user. Upon changing --user to just -u in script problem resolved.
