Add support for all CRD names

[silasbw]

The current swagger client supports only the plural name for CRDs. Extend the client to support singular and shortNames too. Using example/using-crds.js and example/crontabs-crd.json:

// Plural usage, currently supported
await client.apis['stable.example.com'].v1.namespaces('default').crontabs.get();
// Singular (needs support)
await client.apis['stable.example.com'].v1.namespaces('default').crontab.get();
// shortNames (needs support)
await client.apis['stable.example.com'].v1.namespaces('default').ct.get();

See https://github.com/godaddy/kubernetes-client/blob/master/lib/swagger-client.js and https://kubernetes.io/docs/concepts/api-extension/custom-resources/ for more information.
