Move Project and VPC edit forms from list pages to individual resource view pages

In #2405 we moved the edit form for IP Pools from the page showing the list of IP Pools to the individual IP Pool view page.

We need to follow the same pattern for Projects and VPCs.

I actually think we might want to keep the projects page as it is, where the side modal form for editing the project continues to show on the /projects list page.

For IP Pools and VPCs, there's a root view page for each of those resources. Projects, though, don't have a "home" page, and just take you to the /{project}/instances sub-page.
