Enable oidc client registration in hub-auth

[talwinder50]

Hub-auth will act as oidc provider as well where the client like kms will registerr the application
Before using hub-auth with your application, you must register your application with the service. This is done through a registration form in the “developer” or “API” portion of the service’s website, where you will provide the following information (and probably details about your application):

Application Name
Application Website
Redirect URI or Callback URL

Once your application is registered, the service will issue “client credentials” in the form of a client identifier and a client secret.
