Epinio UI

Pre-Requisites

Epinio must be informed of the domain the UI is served on. This can be set by the access controll allow origin property

when installing epinio (helm install epinio-installer epinio/epinio-installer --values <filepath to below>.yaml)
```
global:
  domain: <see epinio docs>
server:
  accessControlAllowOrigin: <domain>
```
at run time (edit the ACCESS_CONTROL_ALLOW_ORIGIN env var of the epinio/epinio-server deployment)
