In previous versions of setuptools (for example 33.1.0) is was possible to use the bootstrap.py script to install setuptools into an environment which contained only Python (no pip, setuptools, or wheel packages installed). This behavior was very helpful for downstream distributors who want to create packages of setuptools. The currently behavior creates a circular dependency (setuptools requires pip which requires setuptools) which makes packaging difficult. Providing a method to install setuptools into a bare Python environment would be very helpful.

My own needs for this is for conda-forge. We create separate conda packages for python, setuptools, pip and wheel so that they can be upgraded independently. Our build order for these packages was python, setuptools, wheel and then pip. The new requirements on pip to install setuptools is causing some issues with this build order.

Added an optional flag to the bootstrap.py script in PR #958 which when specified skips the installation of dependencies using pip. This should solve the issue for re-packagers who are using other tools to install these dependencies.
