pgbouncer - pgbouncer: Apply client_login_timeout to clients waiting for

Log Message:
-----------
Apply client_login_timeout to clients waiting for welcome pkt

Otherwise the clients stay waiting infinitely, unless there is query_timeout set.

This only applies for servers that have never been up.  If server has
been connected once, the query_timeout is only thing that kills clients,
as clients are let freely log in after first connect to server.
