so if there is anything wrong in `--isolation` (e.g., `cgroups/xyz`), it must have been detected
in `MesosContainerizer::create()`, right?

We need this because we skip the check in `MesosContainerizer::create()`

```
    if (strings::startsWith(isolation, "cgroups/")) {
      if (usedCgroups) {
        // Skip when `CgroupsIsolatorProcess` have been created.
        continue;
      } else {
        usedCgroups = true;
      }
    }
```

Or we put this check at there?
