Add cos-dev-61-9733-0-0 to the benchmark tests

Ref: https://github.com/kubernetes/kubernetes/issues/42926

m60 has docker 1.13.1 while m61 has 17.03. This PR adds m61 to the benchmark tests so that we will have more data to compare.

PS: We will support fetching the latest image in an image family in the node e2e tests in the future.

**Release note**:

```
None
