Backport from master: Set the default instance type to t3.medium for AWS

[jeffb4]

This changeset backports 7a42cf4 from master into the 1.16 release branch.

Reasons:

• this change is very low impact
• 1.17 is still in beta
• this change didn't make it into 1.17 anyway
• it would make my govcloud deployments immensely easier, for reasons

I don't know the kops policy on backporting, I'll understand if it doesn't meet criteria to go into 1.16.1 .

Hi @jeffb4. 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.

@jeffb4 unfortunately this is a pretty big change to cherry-pick to a released version.
1.17 is still open though. Would it help to cherry-pick it to 1.17, considering that it should be released in about 1 month or so?

[jeffb4]

Certainly. Should I open such a PR or would you prefer to?

[hakman]

Don't worry. The release notes part is a bit more complicated. Thanks for making the effort to create this PR though.
Closing this in favour of #8656.
