Summary: Extracted basic Env-related tests from mock_env_test and memenv_test into a parameterized test for Envs: env_basic_test. Depends on D58449. (The dependency is here only so I can keep this series of diffs in a chain -- there is no dependency on that diff's code.) Test Plan: ran tests Reviewers: IslamAbdelRahman, sdong Reviewed By: sdong Subscribers: andrewkr, dhruba, leveldb Differential Revision: https://reviews.facebook.net/D58635
