Preserve the order of architectures in the image requests inside the compose requests, i.e. don't transform 'arches' into a set, which has random order. It is not that anyone should really depend on it, but there is also no need to mess with the order, potentially making it harder for humans to match requested arches with compose request content and logs.

"""Koji osbuild integration - builder plugin
|
|
|
|
This koji builder plugin provides a handler for 'osbuildImage' tasks,
|
|
which will create compose requests via osbuild composer's koji API.
|
|
|
|
Included is a basic pure-python client for composers koji API based
|
|
on the corresponding OpenAPI. Although manually crafted it follows
|
|
its terminology closely.
|
|
This client is used in the `OSBuildImage`, which provides the actual
|
|
koji integration to talk to composer.
|
|
|
|
This file can also be used as an executable where it acts as a stand
|
|
alone client for composer's API.
