schema: Import various Affinity definitions from Kubernetes API

From kubernetes/spec/api/openapi-spec/v3/api__v1_openapi.json

Imported with their original names under components.schemas to simplify

```bash
set -euxo pipefail

yq4 -i -P 'del(.$defs.kubernetesAffinity)' config/schemas/config.yaml
c="io.k8s.api.core.v1.Affinity" yq4 -i -P '.$defs[env(c)] = load(".../kubernetes/api/openapi-spec/v3/api__v1_openapi.json").components.schemas[env(c)]' config/schemas/config.yaml
c="io.k8s.apimachinery.pkg.apis.meta.v1.LabelSelectorRequirement" yq4 -i -P '.$defs[env(c)] = load(".../kubernetes/api/openapi-spec/v3/api__v1_openapi.json").components.schemas[env(c)]' config/schemas/config.yaml

while grep -qF '#/components/schemas/' config/schemas/config.yaml; do
	for component in $(grep -oP "#/components/schemas/[^'\"]*" config/schemas/config.yaml | cut -d/ -f4); do
    c="${component}" yq4 -i -P '.$defs[env(c)] = load(".../kubernetes/api/openapi-spec/v3/api__v1_openapi.json").components.schemas[env(c)]' config/schemas/config.yaml
    sed -i "s|#/components/schemas/${component}|#/\$defs/${component}|" config/schemas/config.yaml
  done
done
```
