Disable AppVeyor but keep the config file
AppVeyor builds have stopped. May need appveyor.yml
file
in the default branch to get it going again.
The file will be restored when Windows builds are
working again.
Last failure log has:
HTTP GET to https://gitlab.com/api/v4/projects/23992091/repository/files/.appveyor.yml?ref=d4288632f131277e33818ca4f70c6611afb69d54 returned status code 520:
