[5/6] new: environments - create the environment directory

Commit Message

Jan Tulak March 18, 2015, 6:10 p.m. UTC

Add the environment directory and "empty-files" environment used by
performance/001 test. The empty-files script checks ENV_FILES_NUMBER
environment variable to know how many files it should create.
