* Update OpenVPN role to generate self-contained "unified" .ovpn
  profiles

  * The role now generates .ovpn profiles with embedded CA, certificate,
    key, and HMAC firewall key information. These .ovpn profiles are
    compatible with OpenVPN for iOS and Android, and only a single file
    needs to be transferred to your mobile device.

  * Added explicit route information to the .ovpn profile
