Paul Hinze 4bd4e18def core: use same logging setup for acctests ... We weren't doing any log setup for acceptance tests, which made it difficult to wrangle log output in CI. This moves the log setup functions we use in `main` over into a helper package so we can use them for acceptance tests as well. This means that acceptance tests will by default be a _lot_ quieter, only printing out actual test output. Setting `TF_LOG=trace` will restore the full prior noise level. Only minor behavior change is to make `ioutil.Discard` the default return value rather than a `nil` that needs to be checked for.		2015-12-08 17:50:36 -06:00
