2.1.151

This release brings support for a new --exclude <req> PEX build option
that allows eliding selected resolved distributions from the final PEX.
This is an advanced feature that will, in general, lead to broken PEXes
out of the box; so read up on the --exclude command line help to make
sure you understand the consequences.

This release also brings a fix for --inject-env that ensures the
specified environment variables are always injected to the PEX at
runtime regardless of the PEX entry point exercised.

• Implement support for --exclude <req>. (#2281)
• Relocate environment variable injection to before the interpreter is run (#2260)
