ci/packagespec (hashicorp#9653)

* add packagespec build system

- The majority of changes in this commit are files generated
  by packagespec (everything in the packages-oss.lock directory).

* add .yamllint

* update to packagespec@fd54aea4

* ci: bust packagespec cache

- Change to packagespec results in package IDs that can use
  git tag refs, not just commit refs.

* update to packagepsec@5fc121d0

- This busts all caches, because of a change to the way we
  no longer traverse from tag refs to commit refs, due to
  the potential confusion this can cause.
- See hashicorp/packagespec@fd54aea
  for the original change to packagespec necessitating this.

* update to packagespec@5e6c87b6

- This completes the change to allowing git tag refs
  to be used for source IDs, begun in f130b94

* update to packagespec@4d3c9e8b

- This busts cache, needed to apply previous change.

* remove RELEASE_BUILD_WORKFLOW_NAME

* update packagespec, add watch-ci target

* fix package names (do not refer to EDITION)

* remove EDITION input from packages-oss.yml

* bump package cache, update packagespec

* update packagespec, add 'aliases' target

* update packagespec; less output noise

* ci: give release bundle file a better name

- When performing a release build, this will include the build ID
  as part of the name, making it easier to distinguish from other
  builds.

* ci: create aliases tarball artifact

* ci: cache package metadata files

* ci: add metadata artifact

* ci: bust circleci package cache

* Revert "ci: bust circleci package cache"

This reverts commit 1320d18.

* ci: remove aliases artifact

* ci: use buildID not workflowName to id artifacts

* packages: add BUNDLE_NAME metadata

* do not cache package metadata with binaries

* ci: bump package cache

* ci: debugging

* ci: fix package cache; update packagespec

* ci: update packagespec to 10e7beb2

* ci: write package metadata and aliases

* ci: switch to .zip artifacts

* switch package bundle back to tar.gz (from zip)

- Because of the way zip works, the zip archive was over 2GB rather than under 750MB as with tar.gz.

* bump packagespec, adds list-staged-builds

* update packagespec

* add publish stub + general tidy up

* bump packagespec

* bump packagespec; add make publish-config

* Makefile: tidy up packagespec targets

* pass PRODUCT_REPO_ROOT to packagespec

* bump go to 1.14.6

* packages-oss.yml: use more explicit base image

* bump packagespec to b899b7c1

* bump packagespec to f040ce8f

* packages-oss.yml: pin base image to digest

- This digest is pointed to by debian:buster-20200720
- Using a specific digest ensures that builds use the same
  base image in all contexts

* add release-repo; bump packagespec

* remove BUILD_TAGS and -tags flag

* bump packagespec to e444f742

* bump to go1.14.7

* ci: bump to go1.14.7
