We want to remove clutter from the network panel toolbar by removing or collapsing buttons into a submenu.
Add metrics to the items to see how popular they are.

Items which we want to move:
- "Use large request rows" toggle button
- Waterfall clicking and dragging
- Group by frame button

Items which will probably stay where they are:
- Preserve log button
- Disable cache button
- Offline button
- Throttling drop down menu
