This is to avoid having to explicitly pass it to each subcommand that
needs it. Each codespaces command runs in the context of App, so that's
a point of shared context that we can store state in.
* Rework logging, showing progress, and printing from `codespace` commands
* Change rendering of the general progress indicator so that it's visible on both dark and light backgrounds
* The progress indicator now "spins" faster
