Keep two separate stores to accomplish per-profile sharing:
- Local store, where to push updates manually (save/remove/search)
- Remote iCloud store, where to pull updates from
A profile can be added/removed to/from the iCloud store so that other
devices can push/pull updates to it.
Consequently, updates to the iCloud store will NEVER cause a profile
deletion. Once removed, the profile will stay locally.

Helps with automation. Install the VPN configuration before persisting a
profile, so that the 1:1 reference with OS settings is maintained.
Likewise, uninstall the VPN configuration after removing a profile.
This before-save hook also resolves a problem with multiple imports,
where multiple VPN permission alerts coalesce if no VPN configuration is
installed. Now the first import waits for the permission synchronously.
