Maximum concurrent connections exceeded uploading large files

[Iristyle]

I was trying to establish what the upper limits are for uploading files through winrm-fs and encountered an issue uploading a 50MB file.

WinRM::WinRMWMIError: [WMI ERROR CODE: 2150859174]:

I also ran into this issue uploading a 12MB file.

This is essentially the same as issue #1, which I closed because I feel like this should be addressed in the upstream WinRM gem. For now you can workaround the issue by increasing the per user quota on the Windows guest.

The WS-Management service cannot process the request. This user is allowed a maximum number of 1500 concurrent operations, which has been exceeded. Close existing operations for this user, or raise the quota for this user.

WMF 5 enables copy-file to take -ToSession and -From session parameters, which seems to work fine for me with large files. It would require WMF 5, but that has been released for Windows 7/2008 R2 and up, so it'd have pretty good coverage.

@jakeballard that would be great if we could leverage WMF5 but unfortunately it requires a PSSession and that follows an entirely different protocol: Powershell Remoting Protocol. Whhile it sits on top of WinRM, it is distinctly its own thing.

I do think that #28 will address issues with larger files failing. I'm assuming that @Iristyle hit this on 2k8R2/win7? Which has a very small connection count limit. #28 tracks connections and resets when needed.

fixed with #28
