This is a followup to the testing feature added in #5304.
While it is very nice to have test agent logs to through testing.T.Logf
so that only logs from failed tests are emitted, if a test is hanging or
taking a long time those logs are delayed. In that case setting
NOLOGBUFFER=1 will temporarily redirect them to stdout so you can see
immediate feedback about hangs when running the tests in verbose mode.
One current example of a test where this can be relevant is:
$ go test ./agent/consul -run 'TestCatalog_ListServices_Stale' -v
When tests fail, only the logs for the failing run are dumped to the
console which helps in diagnosis. This is easily added to other test
scenarios as they come up.
