Make private DNS connect timeout configurable
It could take time to connect to a private DNS server if the system
allows 6 syn-retransmissions (net.ipv4.tcp_syn_retries = 6), which
can take time more than 2 minutes.
This change allows us to configure the timeout value via dnsresolver
binder service, and keep the default timeout value the same as the
original design.
