Onboarding - script to get Qt account tokens

This script should ask the user their Qt account email address and then, prompt to get the Qt account password. With this information - make a call to the Qt account login API or another such API using which we can get a relevant token. 

The ultimate goal is to finally obtain the CONAN credentials and JFROG credentials from the Qt account. These CONAN and JFROG credentials must be saved securely in settings.
