Feature request: add settings.kubernetes.node-annotations

[ginglis13]

What I'd Like

I'd like the ability to set annotations on a node in my Kubernetes cluster via Bottlerocket settings, similar to how I can already set labels on a node. The annotations should be have the same user experience as node labels: https://bottlerocket.dev/en/os/1.20.x/api/settings/kubernetes/#node-labels

As toml:

[settings.kubernetes.node-annotations]
annotation1 = "foo"
annotation2 = "bar"

Via apiclient:

apiclient set settings.kubernetes.node-annotations.annotation1=foo \ 
 	settings.kubernetes.node-annotations.annotation2=bar
