Ask for docker-windows in registration
Description
When the user runs gitlab-runner register
we ask a specific set of questions one of them is which executor the user wants to use. In !1296 (merged) we added a new executor docker-windows
which is used for windows.
Proposal
- Add option for the user to set
docker-windows
- Implement this before #3915 (closed) so that #3915 (closed) and set the default cache directory depending on this.
