Output of docker-compose config
(Make sure to add the relevant -f and other flags)

secrets:
  password:
    file: C:\Users\Joaom\teste\secrets\password
  user:
    file: C:\Users\Joaom\teste\secrets\user
services:
  rice:
    image: alpine:3.8
    secrets:
    - source: password
    - source: user
version: '3.6'

Steps to reproduce the issue

1. Install docker toolbox latest release from Docker toolbox repository on a Windows 10 Home Edition computer.
2. docker-compose up -d

Observed result

Secrets are not mounted in the container, because compose is not converting path from Windows to unix Style correctly like it does for volumes.

Expected result

secrets to be mounted successfully.
