We launch one container as part of the test with --pid=host but apparently within that container it launches a copy of "tini" as a process supervisor that prefers to be PID 1. Because it's not PID 1 it logs a warning message about this to the envoy integration test logs that can lead to thinking somehow that a test failure is related when in fact it's completely unrelated. Adding this environment variable avoids the warning.
