Remote-side copy/move feature for SSH/SFTP mounts
Currently the data between two remote paths on the same server is copied or moved through the local client machine, except for the case of moving files within the same filesystem at the remote side.
In case of SSH/SFTP mounts where often a remote shell is available there's a possibility for a large speed optimization if copying and inter-FS movement was also processed at the remote side only. In such case the local instance only starts desired operations at the remote side and later returns the progress from the remote side to display locally.
