In PR#395 we discussed the spelling of archs vs. arches and we agreed to
use arches. This patch only renames the public method `ListArchs`in the
`Distro` interface.
The main reason here is not to make sure we have the right set of build
packages, but rather to make sure the pointer hierarchy (distro->arch->
image type) works as expected.
This information is now provided only when an architecture is specified,
so it is necessary to first obtain object implementing the Arch interface
then object implementing the ImageType interface and then you can get
the filename and mime type.
Tests are changed accordingly to the new API.
Delete unused methods and make types and fields private where
possible. Some code is moved around, but apart from that there
is no change in behavior.
The naming of the distros were moved back into the distro
packages as the common types now only had one user, and this
allowed us to drop some redundant error checking.

Simplify the code by dropping the potential error return. The
constructor simply instantiates some maps, this cannot fail.

Mixing the way to build a distribution with where to get the source
packages from is wrong: it breaks pre-release repos, local mirrors, and
other use cases. To accommodate those, we introduced
`/etc/osbuild-composer/repositories`.
However, that doesn't work for the RCM API, which receives repository
URLs to use from outside requests. This API has been wrongly using the
`additionalRepos` parameter to inject those repos. That's broken,
because the resulting manifests contained both the installed repos and
the repos from the request.
To fix this, stop exposing repositories from the distros, but require
passing them on every call to `Manifest()`. This makes `additionalRepos`
redundant.
Fixes#341
Return errors from all distro's New() functions instead of logging and
returning nil. Also, return errors instead of panicking from
NewRegistry() and NewDefaultRegistry().
These packages (and their tests) shouldn't access the distro package,
because that's cyclic.
Also, these packages should only test the objects they expose.
WithSingleDistro() doesn't follow go's naming convention for creating
objects (New*). Rename it to NewRegistry() and rename the old
NewRegistry() to NewDefaultRegistry().
The idea is that NewRegistry() can be used to create full Registry
objects from outside the package. NewDefaultRegistry() is a convenience
function that creates a Registry with all known distros.
During development of a new distro, we need to test composer against
nightly or beta repositories, but we cannot ship composer itself
with the nightly repository information hardcoded in. At the same
time, we want to distinguish between the system repositories of the
host and the repositories we use to generate images (the host may not
use the same distro/version/architecture as the target, and it may
include custom repositories that the target should not).
We therefore ship per distro repository information that can be
overriden (typically in testing) by dropping files in /etc.
For now use the latest nightlies for RHEL-8.2, we may want to
replace these with the official mirrors for GA eventually.

Introduce a DistroRegister object. For now this does not introduce
any functional changes, as the object is always instantited to be
the same. However, in follow-up patches it will get options.

RHEL and Fedora used different output formats (.ami vs .raw.xz). The job
package assumed `image.ami`, which failed for RHEL.
Change Fedora to use image.raw.xz as well. This makes it consistent, but
we should also get the filename from the distro at some point.
Automatically registering on `init()` is clever, but a bit too magical
and easy to get wrong, because every binary must include all distros
somewhere.
Flip this inside out: distros now have a `New()`, which returns
something that implements the `Distro` interface. The distro package
explicitly creates all of them.
This means that distros cannot import distro itself anymore, because go
forbids import cycles. This only affected `InvalidOutputFormatError`.
Return a generic error for now.
