[Roadmap] Support installation without console

[olljanat]

In very beginning of BurmillaOS project we switched default console to be based on Debian #9 and removed other options.

However, console switching feature still exists and some users are also using their custom console

In most of the environments only reason to have console in-place is to get SSH access to system. Additionally some environments are using it to enable iSCSI support or NFS support

But environments which are not using those features and has other method for remote management (exposing Docker over HTTPS, running GitOps agents, etc) would benefit from option to be able disable console completely as better security and smaller resource usage.

EDIT: This prototype exists in develop branch.
