Title: Default TLS ServerName to the host in the DSN.

A TLS configuration must either have a ServerName or specify InsecureSkipVerify. In most cases, the ServerName value will match the host part of the address in the DSN. This change updates the DSN parser to default the ServerName to the host value provided unless InsecureSkipVerify is specified.
