Chocolatey Wrapper for krew.
This appears to be working. However krew and kubectl seem to be having issues on Windows 10. kubernetes-sigs/krew#156 And this appears to not be fixed until after kubectl 1.16 which is currently un-released. Until this is fixed it doesn't seem approporiate to publish this to Chocolatey.
Uninstall TODO: Have uninstall actually uninstall the plugin. Remove the bin path from the user path.
