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
