Exported env vars might cause edge case bug where it uses a wrong token

[joshua-quek-sonarsource]

Hi @okorach-sonar , this could be the reason why CloudVoyager CLI didnt work for that one terminal instance you had.

Maybe that terminal session somehow exported one of these vars.

I am creating this as a bug, more for discussion first before we decide to remove the use of using such env vars and only allow configs to come directly from CLI flags and/or the JSON config files

++ @joe-tingsanchali-sonarsource also feel free to participate in this discussion.
