Issues with ingress relation

[shipperizer]

when integrating with traefik-k8s a validation issue seems to be happening on the ingress side due to our sent payload

to reproduce simply deploy admin-ui and traefik-k8s and relate them

  - relation-id: 14
    endpoint: ingress
    related-endpoint: ingress
    application-data:
      model: '"stg-identity-jaas-dev"'
      name: '"login-ui"'
      port: "8080"
      redirect-https: "false"
      scheme: '"http"'
      strip-prefix: "true"
    related-units:
      login-ui/0:
        in-scope: true
        data:
          egress-subnets: 10.152.183.219/32
          host: '"login-ui-0.login-ui-endpoints.stg-identity-jaas-dev.svc.cluster.local"'
          ingress-address: 10.152.183.219
          private-address: 10.152.183.219
  - relation-id: 49
    endpoint: ingress
    related-endpoint: ingress
    application-data:
      model: '"stg-identity-jaas-dev"'
      name: '"admin-ui"'
      port: "8080"
      redirect-https: "false"
      scheme: '"http"'
      strip-prefix: "true"
    related-units:
      admin-ui/0:
        in-scope: true
        data:
          host: '"admin-ui-0.admin-ui-endpoints.stg-identity-jaas-dev.svc.cluster.local"'

these are the differences between a login-ui and an admin-ui ingress

login-ui uses lib 2.5, admin 2.6

issue seems to be resolving when upgrading to the latest traefik library 2.13
