feat(console): allow overriding internal storage in boot

[innocenzi]

This pull request adds the ability for external console applications using Tempest to override the internal storage directory, to avoid conflicts when being used alongside another Tempest application.

Additionally, I made it so that the internal storage directory is based on the console application's name. For Tempest, the name is Tempest, so the directory is .tempest (as before).

If the application name was MyApp, it would be a kebab-cased version of it, .my-app.
