Docker: Autoconfiguration for S3 as Primary Storage

[rkilchmn]

It would be great if S3 Primary Storage could be auto-configured similar to the database or Redis settings. Changing the primary storage in the config file after the installation step leads to some strange effects and prohibits a "serverless" deployment where there is no persistent file system other than S3. All file system extensions i looked up for docker requires root access in the container which are not given for serverless deployment options such as AWS Fargate

+1 to add the possibility to configure S3 via env variable like this:

      - S3_KEY=xxx
      - S3_SECRET=xxxx
      - S3_BUCKET=xx-test01
      - S3_ADDRESS=xxx
      - S3_REGION=fr-par
      - S3_SSL=true
      - S3_PORT=443
      - S3_AUTOCREATE=false
