sample config with leafnode and nkeys

[tvojacek]

Is it possible to add to docs sample config with leaf nodes secured by nkey? I have found ugly solution using credential file but it require pretense of JWT token. I kept JWT token from docs and put correct USER NKEY SEED there. Is there better solution?

on leafnode nats.conf

leafnodes {
    remotes = [
        {
           url: "nats-leaf://@server_url:7422"
          account: someuser
         credentials: "server.creds"
        }
    ]
}

where server.creds is copy of example creds from docs

**** this part is keept as it is in docs ****
