Persist the -k/--insecure option in connection profile

[vscheuber]

When adding a new connection profile, we have the option to allow insecure connections by supplying the -k/--insecure option. Unfortunately, this option is not saved to the profile. When we try to export/import any object, we have to specify the flag again even though we are using the same profile.

This feature request is to persist the -k/--insecure option in connection profile so that commands using the profile do not need to explicitly supply it every time.
