Support validating package versions in node conformance test

**What this PR does / why we need it**:

This PR adds a package validator in node conformance test for checking whether the locally installed packages meet the image spec.

**Special notes for your reviewer**:

The image spec for GKE (which has the package spec) will be in a separate PR. Then we will publish a new node conformance test image for GKE whose name should use the convention in https://github.com/kubernetes/kubernetes/issues/45760 and have `gke` in it.


**Release note**:
```
NONE
