service support multiple alias

Description

I have a minio server which supports two domain access like minio:9000, minio1:9000, they point to the same volume, so I need two alias to test it

Proposal

service alias support list to use multiple, like

services:
  - name: minio/minio:latest
    alias:
      - minio
      - minio1

currently I can use the default alias minio-minio and minio__minio to work around, but if 3 are required, it will be great to have the above feature
