Add a cli config option to force a project to use stack, cabal or simply ghc

[jneira]

• To let editors (like vscode) add user faced config option to switch between tools, bypassing the concrete auto discovering. One of the config option would be auto and it would be the default.
• I think it makes sense even after merging the hie-bios branch, although it could be accomplished creating hie.yaml files
• If informed hie should report an error if the project doesn't fullfill the requirementets to use the chosen tool (not having a stack.yaml if you want to use stack and so on)
• Not sure it this issue would supersed force a project type #963

The dev effort is focused in the new ide project so closing this
