feat: support annotations for service catalog meta data

[laszlocph]

People use Kubernetes annotations to store meta data on deployed services.

Gimlet favors https://github.com/laszlocph/osca annotations, but Capacitor should have a configuration option to support any set of annotations.

There are two types of metadata according to Capacitor:

• Annotations to determine the deployed version

  • An annotation that shows what source code version is deployed v1alpha1.opensca.dev/version.sha
  • In what repository: v1alpha1.opensca.dev/vcs.owner and v1alpha1.opensca.dev/vcs.name
  • With a direct link to the version: v1alpha1.opensca.dev/version.link

• Annotations that hold external links Annotations like in https://github.com/laszlocph/osca#external-references This is an arbitrary map of on-screen labels and annotations names in the Capacitor configuration, so Capacitor can render it.
