Support .mobileconfig for IKEv2
- New feature: For macOS and iOS clients, the IKEv2 helper script can now create .mobileconfig files to simplify client setup and improve VPN performance with ciphers such as AES-GCM. - New feature: VPN On Demand is now supported on macOS and iOS. See https://git.io/ikev2 for more details. - The script no longer exports the IKEv2 VPN CA certificate, since .mobileconfig support has been added. - A random password is now generated for the .p12 and .mobileconfig files, and displayed on the screen when finished. User input is no longer required for this password.
