🐛 Ensure node role and fargate policies are included in IAM bootstrap permissions

[adammw]

What type of PR is this?
/kind bug

What this PR does / why we need it:

Adds the possible policies needed to the iam:GetPolicy condition, otherwise reconciliation will fail to fetch the policy when ensuring its attachment.

Which issue(s) this PR fixes (optional, in fixes #<issue number>(, fixes #<issue_number>, ...) format, will close the issue(s) when PR gets merged):
Fixes #5254

Special notes for your reviewer:

This requires all custom extraPolicyAttachments to be known at the bootstrap time. A wildcard iam:GetPolicy may be preferable, or changing the logic of how policies are ensured to not require the GetPolicy permission altogether (see #5266).

Checklist:

• squashed commits
• includes documentation
• includes emojis
• adds unit tests
• adds or updates e2e tests

Release note:

fix: bootstrap IAM policies will include permission to get node and fargate managed policies if applicable

Hi @adammw. 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-sigs/prow repository.
