Describe the bug
Bravetools is able to forward multiple ports to host, however brave units will only show one port in its output

cat >Bravefile <<EOL
service:
  image: brave-base-alpine-edge-1.0
  name: brave-base-alpine-edge
  version: 1.0
  ip: 10.0.0.10
  ports:
    - 8888:8888
    - 7777:7777
  resources:
    ram: 2GB
    cpu: 1
EOL

Deploy unit brave deploy

All forwarded ports are listed by brave units.
