TPv2 Cache Groups table minor updates

[ocket8888]

This makes a few minor changes to the Cache Groups table.

1. Cache Group-to-Parameter relationships are removed in APIv4.0 which TPv2 now uses, so the "Manage Parameters" context menu item has been removed.
2. "Manage" isn't the right word for servers and ASNs, as the view to which it takes the user does not allow manipulations of those relationships, so they've been changed to "View"
3. Implemented the "View Servers" context menu item.

I don't understand how that's possible? The only file I changed has 100% coverage both before and after these changes
