Add Netbsd support (#62)
Add support for the NetBSD Operating System.
Features in this branch:
* Add BSD distro parent class from which NetBSD and FreeBSD can
specialize
* Add *bsd util functions to cloudinit.net and cloudinit.net.bsd_utils
* subclass cloudinit.distro.freebsd.Distro from bsd.Distro
* Add new cloudinit.distro.netbsd and cloudinit.net.renderer for
netbsd
* Add lru_cached util.is_NetBSD functions
* Add NetBSD detection for ConfigDrive and NoCloud datasources
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
