Mihaela Stoica c8d86baeee CP-19086: More improvements to the PVS cache UI
- in the ConfigurePvsSiteAction, we now check if a site still exists, before trying to configure it
- added a CollectionChanged event handler in the Cache configuration dialog, and if we observe that a site has been added, we add it to the dialog as a new page
