Connection profile - bugs and missing values

[dzikowski]

1. CA URL in connection profile starts from http://, even if TLS is enabled (it should be https:// in this case)
2. missing orderers section (required when service discovery is disabled - for instance in dev mode)
3. missing channels section (required when service discovery is disabled)

When all above issues are fixed, a Node.js client could use it with service discovery disabled

:wave: I completely agree with the issue. :+1:

Side note: After doing 2 and 3 it would be good to check if it behaves well when service discovery is on. I remember that we had some issues/discussions while ago with @gzhk about it. Maybe he will guide us and update with pitfalls found back then?
