[AppStream] Adding QA information to a component

[Richard Hughes]

Hi all,

Some advice please: The LVFS ships metadata in AppStream format, and I
think it's 100% comformant now. I'm thinking how to do a new requested
feature where we can add who has checked and QAd a specific component
release.

For instance, a specific firmware release might be tested by:

 * The device vendor on Windows 10
 * The SUSE QA team on Linux x64
 * The RHEL QA team on Linux ppc64le

Of course I could sprinkle that in the <release> section as
<x-tested_by> or something, but I thought discussion here might be
useful. A strawman:

<release>
 <tested_by date="2020-07-02">
  <name>Red Hat QA</name>
  <value key="machine">Lenovo Thinkpad P1</value>
  <value key="distro">RHEL-9</value>
  <value key="architecture">ppc64le</value>
 </tested_by>
</release>

Other ideas very welcome. Thanks!

Richard.
