docker: mkdir /var/lib/docker/volumes/[my-profile]: read-only file system

I ran into this error on OSX.

From offline chat with @medyagh we concluded it was a Docker issue, and a restart of Docker resolved the issue.

Opening this issue to formally track improving Minikube's output message to better guide the user (e.g. suggest a restart of Docker).

😿  minikube is exiting due to an error. If the above message is not useful, open an issue:

I agree and this will need to be adressed.

Narrowing the scope down to something more tangible.
