Update instance_groups.md

[ranshn]

the description and link for spotAllocationStrategy are currently taken from the Spot Fleet documentation, while kops uses EC2 Auto Scaling groups. these are two different tools/APIs, so I am proposing a fix to the readme file that would correct spotAllocationStrategy to point to the ASG documentation instead.

Hi @ranshn. Thanks for your PR.

I'm waiting for a kubernetes 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.

Thanks @ranshn! This looks pretty good. Since you're in there, would you be up for adding an example of a complete mixedInstancePolicy config, as most of the other section have, so users can copy and paste and change each param? I don't have experience with them but I think that could be useful in addition to your cleanup.

Done! let me know if this lgty or if you had something else in mind? maybe cut the non-mixedInstancePolicy parts out of the example?

I think it probably makes most sense for users getting started as a full useful stanza that'll launch a full blown instance group.
