/**
 * Constructs a new secure client socket and connect it to the given
 * host on the given port. The returned Future is completed with the
 * RawSecureSocket when it is connected and ready for subscription.
 *
 * The certificate provided by the server is checked using the certificate
 * database provided in [SecureSocket.initialize], and/or the default built-in
 * root certificates. If [sendClientCertificate] is
 * set to true, the socket will send a client certificate if one is
 * requested by the server. If [certificateName] is the nickname of
 * a certificate in the certificate database, that certificate will be sent.
 * If [certificateName] is null, which is the usual use case, an
 * appropriate certificate will be searched for in the database and
 * sent automatically, based on what the server says it will accept.
 *
 * [onBadCertificate] is an optional handler for unverifiable certificates.
 * The handler receives the [X509Certificate], and can inspect it and
 * decide (or let the user decide) whether to accept
 * the connection or not.  The handler should return true
 * to continue the [RawSecureSocket] connection.
