Spaceship-prompt: `Cannot connect to the Docker daemon`

Current behavior

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running? 

Expected behavior

Do not show docker info if docker daemon is not running

Same here, I see it happens when there's a docker-compose.yml or Dockerfile in the directory but I guess it appeared after a recent automatic update because I didn't get this before with this same directory.

There seems to be a change between Docker client 19.03.8 (edit: I've pinned it down to 19.03.12) and 19.03.13 where, if docker cannot connect to the host, the error message is printed to STDOUT rather than STDERR.

This is causing the "Cannot connect" message to end up in the docker_version variable here: https://github.com/denysdovhan/spaceship-prompt/blob/master/sections/docker.zsh#L61

I hope it's the right place (so many docker related repos 😛), but I've created an issue on docker/cli about the issue: https://github.com/docker/cli/issues/2777

For those of you who are stumbling across this issue and don't really care much about the docker version can simply disable the docker section using this environment variable.
