ARM and other arch's support

[gtrubach]

Hello,

I see in code that kubectl arch is hard-coded to amd64. Is it possible to make it download kubectl depending on agent arch? As I understand os.arch() should return correct architecture and if it used, correct kubectl will be downloaded.

@DS-MS Any particular reason why we stopped at amd64?

Any other action which may have the same problem?

I saw several, and all of them have hard-coded amd64 arch for kubectl download. For instance:

• https://github.com/Azure/setup-kubectl
• https://github.com/Azure/k8s-lint

@azooinmyluggage @gtrubach I believe we hard-coded them to support hosted runners in the beginning. We can start supporting this, with the Self hosted runners made GA.

@gtrubach would you be willing to raise a PR for the same? 😃

@DS-MS Sorry for long silence, will try to create a PR this weekend.
