TSL handling

[larshp]

Suggest one of

A: if port 443 is specified, and useTLS is false, exit with error "set useTLS to true"
B: if port 443 is specified, and useTLS is false, automatically set useTLS to true

I guess HANA will not be exposed on port 443 unless its TLS, so lets help the user in the right direction?

any thoughts? I can help with a pull request

I have some good news: we just implemented option B with the latest PR. This now matches other HANA interfaces that automatically enable TLS on port 443.
