Previously we'd pass the matrix variant to the backend cluster module which is currently unsupported by the consul module. Instead we'll always pass the ubuntu/amd64 AMI ID to the consul backend module.
This should resolve the enos-verify-stable matrix failures here https://github.com/hashicorp/vault/actions/runs/3448137968/jobs/5754873688#step:11:191

Here we make the following major changes:
* Centralize CRT builder logic into a script utility so that we can share the
logic for building artifacts in CI or locally.
* Simplify the build workflow by calling a reusable workflow many times
instead of repeating the contents.
* Create a workflow that validates whether or not the build workflow and all
child workflows have succeeded to allow for merge protection.
Motivation
* We need branch requirements for the build workflow and all subsequent
integration tests (QT-353)
* We need to ensure that the Enos local builder works (QT-558)
* Debugging build failures can be difficult because one has to hand craft the
steps to recreate the build
* Merge conflicts between Vault OSS and Vault ENT build workflows are quite
painful. As the build workflow must be the same file and name we'll reduce
what is contained in each that is unique. Implementations of building
will be unique per edition so we don't have to worry about conflict
resolution.
* Since we're going to be touching the build workflow to do the first two
items we might as well try and improve those other issues at the same time
to reduce the overhead of backports and conflicts.
Considerations
* Build logic for Vault OSS and Vault ENT differs
* The Enos local builder was duplicating a lot of what we did in the CRT build
workflow
* Version and other artifact metadata has been an issue before. Debugging it
has been tedious and error prone.
* The build workflow is full of brittle copy and paste that is hard to
understand, especially for all of the release editions in Vault Enterprise
* Branch check requirements for workflows are incredibly painful to use for
workflows that are dynamic or change often. The required workflows have to be
configured in Github settings by administrators. They would also prevent us
from having simple docs PRs since required integration workflows always have
to run to satisfy branch requirements.
* Doormat credentials requirements that are coming will require us to modify
which event types trigger workflows. This changes those ahead of time since
we're doing so much to build workflow. The only noticeable impact will be
that the build workflow no longer runs on pushes to non-main or release
branches. In order to test other branches it requires a workflow_dispatch
from the Actions tab or a pull request.
Solutions
* Centralize the logic that determines build metadata and creates releasable
Vault artifacts. Instead of cargo-culting logic multiple times in the build
workflow and the Enos local modules, we now have a crt-builder script which
determines build metadata and also handles building the UI, Vault, and the
package bundle. There are make targets for all of the available sub-commands.
Now what we use in the pipeline is the same thing as the local builder, and
it can be executed locally by developers. The crt-builder script works in OSS
and Enterprise so we will never have to deal with them being divergent or with
special casing things in the build workflow.
* Refactor the bulk of the Vault building into a reusable workflow that we can
call multiple times. This allows us to define Vault builds in a much simpler
manner and makes resolving merge conflicts much easier.
* Rather than trying to maintain a list and manually configure the branch check
requirements for build, we'll trigger a single workflow that uses the github
event system to determine if the build workflow (all of the sub-workflows
included) have passed. We'll then create branch restrictions on that single
workflow down the line.
