Describe the problem you'd like to have solved

Auth0 oidc backchannel logout configuration can be parameterized in more precise way than this provider allows.

The Auth0 Management API allows to set them as a following structure

    "backchannel_logout_urls": [
      "string"
    ],
    "backchannel_logout_initiators": {
      "mode": "custom",
      "selected_initiators": [
        "rp-logout"
      ]
    }
  },```
  
go auth0 SDK has the support for it, added https://github.com/auth0/go-auth0/pull/384 

### Describe the ideal solution

https://github.com/auth0/go-auth0/releases/tag/v1.5.0 freshest release of go sdk contains the support for setting the oidc logout parameters properly. Please adapt it
