Keep the newlines on configuration options so that Neutron can read them

If we remove the newlines neutron can't read the configuration options and you end up with it throwing exceptions and exiting:

```
# grep rpc_conn_pool_size *
neutron.conf:rpc_conn_pool_size = 30# Seconds to wait for a response from call or multicall
```

```
