Improve parallel performance of Connectivity filter
ParaView counterpart to vtk/vtk#17204 (closed).
To test that it continues to work (not the performance improvement part):
- Connect to remote server with number of processes > 1
- Add Wavelet
- Add Contour
- Add Connectivity
- Color Connectivity by "RegionId"
You should not see any processor boundaries on the contours (they would be obvious).
