IMPALA-7943: Bump the default client timeout set on impala-shell

As part of IMPALA-7555, we added a default socket timeout of 5 seconds
when connecting to an impalad. Under heavy load with kerberos and SSL
enabled, we could hit this default timeout. This change bumps up the
timeout to 60 secs to make the impala-shell more robust.
