Gyu-Ho Lee 2779341250 e2e: clean up, return all lines in error
1. change file names
2. now if sub-command errors, the test will receive all
lines from stdout and stderr.

Expected output:

```
read /dev/ptmx: input/output error (expected key2, got ["key1\r\n" "val1\r\n" ""])
```

3. change how we check GRPC timeout (only bypass timeout error when we give 0
timeout)
