All composes now include the image size in their status response. The
image size will be 0 except for finished composes where it will be the
file length in bytes.
In order to maintain parity with lorax the api needs to reply with an
error message equivalent to that used by lorax. Error messages are now
returned inside an error object that contains an id, message, and
optional status code.
For some routes, there are errors when no url parameters are passed. The
httprouter was using named parameters of the form /:param which does not
match for empty parameters. Now, it has been updated to use the
catch-all parameters of the form /*param. This change allows the case of
no parameters. However, parameters will now include a "/" as
their first character. This needs to be removed from the string in the
route handler.
In order to provide the proper error message for
/modules/list/<modules>, searching for the modules needed to be updated.
The requested modules and known packages are iterated over and if there
is a match the module is added to the response. Also, the found module
is dropped from the list of requested modules. If this list is not empty
after searching all of the modules then an error is returned containing
the name of the non-existant module.
Wrap the channel in Pop and Push methods, so it is not exposed to
the callers. PushCompose replaces the old AddCompose for consistency,
and PopCompose simply reads from the other end of the channel.

Let the weldr API take the store as an argument, rather than create it
itself. This will allow us to share the store with the jobqueue API in
follow-up patches.

This encapsulates all the state of osbuild, no longer just the state specific
to the weldr API. Make it a first class type, preparing for direct access from
both the weldr and jobqueue APIs.

Each output type will have its own translator from a blueprint to
a pipeline.
In the future, we may also want to distinguish between different
base distributions and architectures, but for now we keep it
simple and hardcode to a given one.
Some placeholder output formats are added, these have not been
tested or reserached, but are included to show how the it will
all fit together.

This will contain all the translation logic from blueprints to pipelines,
which will constitute the main part of composer, so let's separate that
out from the API.

Go doesn't really do variants, so we must somehow emulate it. The
json objects we use are essentially tagged unions, with a `name`
field in reverse domain name notation identifying the type and a
type specific 'options' object.
In Go we represent this by having an BarOptions interface, which
implements a private method `isBarOptions()`, making sure that only
types in the same package are able to implement it. Each type FooBar
that should belong to the variant implements the interface, and a
constructor `NewFooBar(options *FooBarOptions) *Bar` that makes sure
the `name` field is set correctly.
This would be enough to represent our types and marshal them into
JSON, but unmarshalling would not work (json does not know about
our tags, so would not know what concrete types to demarshal to).
We therefore must also implement the Unmarshall interface for Bar,
to select the right types for the Options field.
We implement his logic for Target, Stage and Assembler. A handful
of concrete types are also implemented, matching what osbuild
supports.

This way it can be correctly exposed in the API. We listen on a channel
from the job-queue, where status updates are pushed when the worker is
running/finished (or, in the future, failed).

This means they are serialised and restarted in case composer is
crashed/restarted. We also need this in the future to track their
state, and allow them to be listed in the UI.

For now we will hardcode the org.osbuild.local target, so we might
as well fix this up front.
We do not yet support any target types, but for testing purposes we
claim to support 'tar', and we pass a noop tar pipeline to the worker.
This makes introspecting the job-queu api using curl a bit more
pleasant.

This is by no means done, and needs more tests, docs and bugfixes,
but push it early so we have a common base to work on.

The list of changes between the committed blueprint and its workspace
are returned when a user requests the diff. Each change includes the
new(added) or the old(removed) package.
If a package had version "*" and its name-version would be "name-*".
This would match all packages containing "name" in their name. Instead
the name-version is "name-*-*" so it matches any version of the package.
Keep main.go files under cmd/ and internal libraries under internal/.
This will allow us to add more exutables under cmd/ (whereas only one
was possible when main.go was kept in the root).
