Support more AWS related env vars

[fenak]

Might fix #154

As briefly discussed on https://github.com/PrivateBin/docker-nginx-fpm-alpine/pull/142, there could be some missing env vars that need to be available for the SDK to interact with AWS. This PR adds more of them.

This probably doesn't cover every single use case, but should be a good step on the right direction.

For reference:

• Env vars mentioned on Aws\Credentials\CredentialProvider: https://github.com/aws/aws-sdk-php/blob/d46961b82e857f77059c0c78160719ecb26f6cc6/src/Credentials/CredentialProvider.php#L46-L53
  • AWS_ROLE_ARN
  • AWS_ACCESS_KEY_ID
  • AWS_PROFILE
  • AWS_ROLE_SESSION_NAME
  • AWS_SECRET_ACCESS_KEY
  • AWS_SESSION_TOKEN
  • AWS_WEB_IDENTITY_TOKEN_FILE
  • AWS_SHARED_CREDENTIALS_FILE
• Env vars related to deployments in AWS ECS
  • AWS_CONTAINER_AUTHORIZATION_TOKEN

Thanks heaps @elrido, I was able to test the new image and it works. It is possible to deploy the new PrivateBin release in AWS using an IAM role now with the patched image. 🙌
