Letsencrypt Pebble Versions Save

• Always send Link: rel="index"
• Implement orderNotReady and badPublicKey errors
• Add linting, test coverage, code of conduct and make lint fixes
• Use pre-built release versions of pebble and pebble-challtestsrv in docker-compose.yml
• Add AppVeyor support to auto-publish Windows Docker images

This release enables all of the behaviour previously gated behind -strict as defaults. If you were not running Pebble 1.0.x with -strict already you may find this is a breaking release that requires client bugfixes. If you were previously running Pebble 1.0.x with -strict you should find 2.0.0 is a drop-in upgrade.

This patch revision fixes the Docker image deployment from CI.

• fix: publish on Docker - https://github.com/letsencrypt/pebble/pull/199

Following the decision to switch Pebble to using Semantic Versioning we're happy to announce the v1.0.0 release.

Moving forward we will no longer be publishing date based git tags or docker image tags and will instead only publish semver git releases and docker image tags.
