In packer v1.8.5, the bucket's description was not properly set in the
bucket object we use for HCP, therefore all the buckets created by
Packer did not have their description updated.

Fingerprints are how we link a packer build to an iteration on HCP.
These are computed automatically from the Git SHA in the current state,
and are unique to the bucket/iteration.
The main problem with this approach is that while sound in theory, it
quickly falls apart when users want to run the same build configuration
twice, but expect a new image to be created.
With the current model, this fails, as the iteration with the current
SHA already exists.
While this is solvable through environment variables, or by committing a
change to the repository, we think this is not clear enough, and causes
an extra step to what should otherwise be a simple process.
Therefore, to lower the barrier of entry into HCP, we change this
behaviour with this commit.
Now, fingerprints are randomly generated ULIDs instead of a git SHA, and
a new one is always generated, unless one is already specified in the
environment.
This makes continuation of an existing iteration a conscious choice
rather than something automatic, and virtually eliminates conflicts such
as the ones described above.
The iteration structure that we use for linking a packer build to an
iteration on HCP defines a `Labels' attribute, which is never set nor
read from at any point.
Since it is unused, we remove it in this commit.
This commit irons out one of the pain points of the HCP rework by
introducing a HCPPublisher interface, implemented both by the JSON Core,
and the HCL2 PackerConfig, which keeps a map of the build names used by
Packer to the build names pushed on HCP.
This in turn lets us go back to the old implementation of the GetBuilds
function, which returns a list of (filtered) builds, and eventually an
error if something went wrong while processing.
Related to the previous behaviour problem, this changes how the status
of a build is set on HCP Packer, as a cancelled build is different from
a failed one, we can set it to the appropriate state on cancellation.
As a follow-up to tracking the template type for an iteration, we
actively check that it remains consistent between two invocations of
packer, and reject the update if it is not the case.
In order to ensure users keep the same templates between two packer
invocations for a single iteration, we start tracking the type of
template used when building images.
In JSON templates, we register the builds to process on HCP at the
initialisation of the Registry.
However, during the HCP breakout, this code was duplicated with a slight
difference for the JSON templates, and the build names were registered
once during initialisation, with the expected full name, and once at the
start of PopulateIteration, with the truncated name.
This caused a bug when processing a template that contains a builder
with both a name and a type, as both would be registered, but only one
would complete, leading to the iteration being unable to complete.
The ancestry inferral code relied on HCP datasource outputs for deciding
what would be the ancestry for an image built with HCP.
This brings a dependency into the hcp package, which is not really
necessary as we only need a few information from those entities, hence
this commit removes the full dependency on the structures, in favour of
more focused data structures where we only cherry pick what is necessary
for this code.
This commit reorganises the code for both the registry/API and the
Orchestrator/Registry.
The main difference with the previous version is how stuff is exposed.
Now we only expose a Registry interface to the outside (previously named
Orchestrator), which has several implementations: null is the default,
and is returned if HCP is not enabled.
The other implementations being HCL/JSON, both private to the hcp
sub-package.
The api (previously `registry') is the set of functionality that
abstracts and calls the HCP API.
It was meant to be merged with the `hcp' package, but because of a
dependency loop with the datasources, both are separated for now.
