"Bootstrap options" are a small set of options whose values are useful when registering other
options. Therefore we must bootstrap them early, before other options are registered, let
alone parsed.
Bootstrap option values can be interpolated into the config file, and can be referenced
programatically in registration code, e.g., as register.bootstrap.pants_workdir.
Note that regular code can also access these options as normal global-scope options. Their
status as "bootstrap options" is only pertinent during option registration.
