Shorten printed Windows paths on docker help cmd

Browse source 
This makes use of `%USERPROFILE%` as a substitute for
`~` on Windows and prints shorter strings for default
cert paths etc.

Also removes string escaping/quotes around default
path values printed in `docker help` command as they
are not really necessary and adds double backslashes
(\\) on windows.
