Would passing expected nodes to elasticsearch as a command line parameter like this work?

"elasticsearch -Des.gateway.expected\_nodes=2"

You should be able to pass expected nodes to elasticsearch as a commandline parameter like so:

```
elasticsearch --gateway.expected_nodes=2

```

Using `-Des.gateway.expected_nodes=2` should work 🙂

I doubted whether this would work because when i tried the option -Des.bootstrap.mlockall=true it did not work, any idea why this did not work?
