This adds a wrapper to Builder::from_env so a variable other than
RUST_LOG can be used
This also updates the log crate to the latest, where the feature has
been changed to "kv_unstable_std", as well as updates env_logger to 0.9
I added a WriteAdapter struct into the tests to capture log output into variables for testing
