Set snat to false

**What this PR does / why we need it**:
- the [version](e8bea554c5) of the portmap plugin included with calico CNI version `v1.9.1` doesn't have `noSnat` config option, it has `snat` which is not specified (which is the case without this PR), [will be set to true by default](https://github.com/containernetworking/plugins/tree/master/plugins/meta/portmap#usage) , so we need to explicitly set it to `false`
