v1.31.0

This is a tiny release before the really big release, and also the last before the big v2.0.0. The most interesting things in this release are the new preliminary health endpoint to allow monitoring in K8s (and others), and the removal of upx binary packing (which was causing erroneous virus flagging). Aside from that, the go-smtp library did a breaking-change upgrade, which required some work to get working again.

• Preliminary /v1/health API endpoint for service monitoring (no ticket)
