v0.8.0

Security Fixes

• Bump LTS Kernel 4.15.0-72.81 #320
  See https://usn.ubuntu.com/4210-1/
• Disable Password Auth in SSH #321
  This addresses a security concern, #262 brought to our attention by @majkrzak.
  If you need to override this secure default, a write_files to /var/lib/rancher/k3os/ssh/sshd_config should do the trick.

Documentation Fixes

• HTTPS_PROXY Typo http_proxys what? #311

Bug Fixes

• Fix Broken Upgrade Scripts #327

Features and Enhancements

• Updated Tooling #292 htop, rng-tools, qemu-guest-agent
  Additionally, the parametrizable toolbox script to pull down an arbitrary container to twiddle some bits contributed by @bhale
  The services for rng-tools (aka rngd) and qemu-guest-agent are not enabled unless a corresponding entry in /etc/conf.d is present.
• Refactored Usage of LinuxKit Bits #297 metadata is now built directly from LinuxKit source
• Refactored k3OS Commands Into Multi-call Binary #303
  • os-config is now k3os install
  • ccapply is now k3os config
  • rc.init is now k3os rc with code from fork of LinuxKit rolled into the project (invoked early during boot, may be replaced eventually with bash scripts)
• Build with go 1.13 #312
• Publish Container Images #323
  Yet another key bit of functionality supporting the forthcoming operator (upgrades).
