[V2] chore: Add ability to point at different image for servercore 🔧

[jmclong]

What type of PR is this?
/kind cleanup

What this PR does / why we need it:
Currently, we depend on "cached" version servercore from the GCR to build the driver image for Windows. Most Go programs require only the binaries from nanoserver, but also one binary (NetApi32) from servercore. "servercore" is very large, so we pull from the "cached" version to speed up builds. This cached version is built by the kubernetes repo for the linux/amd64 and linux/arm64 platforms.

However, in ADO, we are only able to pull from MCR images. In order to provide this functionality while preserving the speedup from using the servercore-cache outside of ADO, I added the SERVERCORE_IMAGE and SERVERCORE_PLATFORM build-args to let me set SERVERCORE_PLATFORM=windows/amd64 and SERVERCORE_IMAGE=mcr.microsoft.com/windows/servercore.

Requirements:

• uses conventional commit messages
• includes documentation
• adds unit tests
• tested upgrade from previous version

Hi @jmclong. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

First test failure is related to hiccup installing "kind:"

curl -Lo ./bin/kind https://kind.sigs.k8s.io/dl/v0.11.1/kind-linux-amd64

I tried it on my machine and it was successful. I think mitigation would be to retry installing.

Second failure in pull-azuredisk-csi-driver-external-e2e-single-az-mainv2:

aks-engine indicates that ARM deployment failed. I think this would also be a sporadic issue.

Timed out on make e2e-teardown, seems like unrelated to this change.
