2.15.0

This release enhances the REPL your PEX drops into when it either
doesn't have an entry point or you force interpreter mode with the
PEX_INTERPRETER environment variable. There is now clear indication
you are running in a PEX hermetic environment and a pex command
added to the REPL that you can use to find out more details about the
current PEX environment.

• Add PEX info to the PEX repl. (Add PEX info to the PEX repl. #2496)
