Description

Use plugins in the headlamp when base-url option is enabled.

Impact

When the base-URL option is enabled - plugins don't draw in the Headlamp UI.

Environment and steps to reproduce

Set-up: Kubernetes 1.23, nginx-ingress controller, Keycloak OIDC enabled Headlamp in cluster deployed with settings:

1. deployment:

     args:
       - '-in-cluster'
       - '-plugins-dir=/headlamp/plugins'
       - '-oidc-client-id=<client_id>'
       - '-oidc-client-secret=$(CLIENT_SECRET)'
       - >-
         -oidc-idp-issuer-url=https://<keycloak_url>/auth/realms/<headlamp_realm>
       - "-base-url=/headlamp"

2. ingress:

     spec:
       rules:
         - host: >-
            <dns_name>.com
           http:
             paths:
               - path: /headlamp
                 pathType: Prefix
                 backend:
                   service:
                     name: edp-headlamp
                     port:
                       number: 80

Additional information

I tried to copy plugins from the custom directory (/headlamp/plugins) to the Headlamp base plugins directory, but it did not help to resolve this issue.

I'm pretty sure this works now.
