#2013 Support scrubbing all PEX_* env vars
Issue created by
jsirois
In order to scrub PEX_* env vars to keep a PEX hermetic, someone launching a PEX must either clear the environment which takes care - many things need PATH / HOME, etc. If either a PEX could be built with a PexInfo setting to ignore PEX_* env vars or the Pex runtime provided away to turn them off, or both, then locking down a PEX would be easier.
