Cortex does not compile for Windows

I think the problem in grafana/loki#193 is that compilation for Windows was attempted, and the code has not been ported to Windows.

If someone would like to confirm that, I change the issue title.

refer the comment, the diskcache.go use some func which not port to Windows.

@bboreham we'd like to contribute to make Loki's promtail work on Windows and this ticket is the blocker for that. You tagged this ticket "help wanted", do you have something in mind for the implementation? If you gave some directions my team would gladly contribute a PR!

Hi, thanks for the offer!

Roughly: find all the parts which don't compile on Windows, then either reimplement or stub out, and add build constraints and/or the file naming convention to build the right file on the right platform.

Extend CI to cross-compile, at least as a check to see everything compiles.

Trying to resolve this one!
