954b2acb7c Fix for IKEv2 
- Fix an issue where multiple IKEv2 clients behind the same NAT cannot
  connect simultaneously to the VPN server. Note that before this fix,
  this issue only occurs when using an IP address (instead of a DNS name)
  for IKEv2 for the VPN server.
- This issue is found to be related to Libreswan's matching of local IDs
  when checking connections. A local ID with '@' prefix has type ID_FQDN,
  which does not match the ID_IPV4_ADDR type that the peer expects. This
  prevents connection switching from working correctly for the scenario
  above. Removing the prefix fixed the issue.
- Fixes #924

a44c1ea473 Update IKEv2 script 
- Improvement: If the script is run using sudo, export the VPN client
  config files to the user's home directory instead of "/root", and set
  owner/group so that users can more easily download the config files.

5e1b3e1ae9 Update IKEv2 script 
- Apply fix for NSS bug on Ubuntu 18.04. Ubuntu 18.04 has NSS (libnss3)
  version 3.35, which has a bug with iteration counts that results in
  "incorrect password" errors when trying to import a generated ".p12"
  file to Windows. To fix this, we install newer versions of libnss3
  related packages from the official Ubuntu repo.
