Multiple Domains per app

[mms-gianni]

What
It should be possible to run an app on multiple domains. There should be a (+) button adding more rows for additional domains. Similar to environment vars.

The domains should be passed as an array to the API ("domain" is replaced with "ingress"

ingress: [
{
  domain: one.example.com,
  SSL: true
},
{
  domain: two.example.com,
  SSL: false
},
]

The operator is already ready for multiple domains
