ProcessRenderer was coloring connected nodes because we need that info
for rendering details panels. However, the main process topology view
renderers depending on ProcessRenderer were also doing coloring
themselves. For the 'processes' topology that was literally
duplicating work. For the 'processes-by-name' topology that was
throwing away the process coloring, and then coloring at the name
level.
Solution: remove the coloring from the ProcessRenderer, thus
eliminating the duplicate/thrown-away work, and introduce a
ColorConnectedProcessRenderer which is only used in places that
populate details panels.
* Add filters for pseudo nodes.
- Don't filter the internet node as a pseudo node.
- Rename pseudo filter to unmanaged/uncontained.
- Review feedback
- Move the FilterFoo funcs into the tests
- Drop the 'nodes' from filter labels.
* Fix experimental
