* Add new cloudinit.distro.netbsd and cloudinit.net.renderer for                
  netbsd

This branch has been tested with:                                               
                                                                                
- NoCloud and OpenStack (with and without config-drive)                         
- NetBSD 8.1. and 9.0                                                           
- FreeBSD 11.2 and 12.1                                                         
- Python 3.7 only, because of the dependency oncrypt.METHOD_BLOWFISH.           
  This version is available in NetBSD 7, 8 and 9 anyway
