[Paraview] Disconnect and save animation

[Utkarsh Ayachit]

Folks,

I am trying to get a feel is anyone uses this functionality at all. If
not, we'd like to remove it as it simplifies a few interactions,
besides reducing code complexity.

The functionality I am referring to allows one to disconnect from a
remote server and then save animation on the server before the server
exits but after the client has disconnected.

Thanks
Utkarsh
