v2.4.0

• Create a script that can sign certificates with the help of a local certificate authortiy.
  • It is now possible to work completely offline.
  • We can now create certificates for localhost.
• Restructure and add a lot of documentation.
• openssl is now a symlink to libressl in the Alpine images.
  • This is done to simplify the rest of the scripts since the arguments are the same.
