Add matchExpressions to Bundle's spec.target.namespaceSelector

[sathieu]

Currently, bundle has:

spec:
  target:
    namespaceSelector:
      matchLabels:
        linkerd.io/inject: "enabled"

We need support for:

spec:
  target:
    namespaceSelector:
      matchExpressions:
      - key: kubitus-project.gitlab.io/inject-ca-bundle
        operator: NotIn
        values:
        - 'false'

I think this was discussed in #258 - as this new feature supports all types of selectors. It would make sense to add this IMO, and I also think it could be added non-breaking. PRs welcome! 😸

@ocampeau Could you please take a look at this feature request 🙏?

I think it could be a nice addition yes. This can definitely be done in a non-breaking fashion. The Kubernetes libraries already provides the types for that.
