Support to delete file version history

[matsla]

It seems to be supported to delete versions on a listitem but not a file.

We are currently implementing an archive solution and one of the steps is to remove file version history, when will this be supported?

PNP PowerShell you can remove a single file versions and all versions for a file

@matsla : in the interest of time, can you check in PnP PS what API calls are used for this

[matsla]

@jansenbe : PnP PS use CSOM assemblies Microsoft.SharePoint.Client.File object to load all versions and then delete

@matsla : Just added DeleteAll, DeleteByID, DeleteByLabel, RecycleByID, RecycleByLabel and RestoreByLabel methods for IFileVersionCollection. These will be part of the nect nightly, closing this issue now.
