[Paraview] paraview python script : Delete(renderView1) does not free memory

[Utkarsh Ayachit]

Delete() will only remove the render view, not all other proxies that were
created as part of the state loading operation. The following script should
do the trick:

--------------------------------------------------------------------------------
from paraview.simple import *

def ResetSession():
    pxm = servermanager.ProxyManager()
    pxm.UnRegisterProxies()
    del pxm
    Disconnect()
    Connect()

for i in range(0, 10):
    ResetSession()
    servermanager.LoadState("/tmp/sample.pvsm")
    renderView=SetActiveView(GetRenderView())
    Render()
--------------------------------------------------------------------------------
