Add more actions menu on IP pool detail that lets you edit

Right now you can only edit from the list view. Check other resources with a detail view to see if we need to make this change, like VPC and instance.

I had a whole long thing here where I was wondering how we wanted to handle the URL pattern, but I think I've got it sorted.

Essentially, we can either leave the "Edit" action on the list page's dropdowns, or remove it. If we leave it in, clicking on it will take the user to the View page for the IP Pool, in the edit mode (so, with the sidebar). The sidebar won't show up on the IP Pools list view.

We will need, on saving the edit form, to reload the page with the new IP pool name in the URL. I feel like we've done that before, but haven't found a spot in the code where we do that yet.
