Add support for FTP server

[louiemej]

Hi I would like to request to add ftp support for uploading and downloading files.

I believe this is a good way to upload/download files when having multiple replica of Adonisjs instances (load balancing)

Adonis.js is a node.js framework, so you can use any npm package to do this.

Currently the ACI ingress does not support FTP server (in passive mode). It would be very nice to have support for this in ACI to run small services like FTP directly in a container instance. Also support for a larger port range than the 10 ports currently supported.
