Support TLS/SSL

[kwent]

Hi @ufukomer, thanks for this piece of software !

Would be nice to support TLS/SSL configuration as well

Cf. https://www.cloudera.com/documentation/enterprise/latest/topics/impala_ssl.html
Cf. https://github.com/apache/thrift/blob/c8e0207053a26f206d6515313747b7e1999a01d5/lib/nodejs/lib/thrift/connection.js#L249

I cannot use this without SSL support - it would be great to have it - I am left without a client

@jmicco I've asked for a working cluster but no one helped thus I could not configure these security layers (#17 (comment)).
