Code review comment for ~emitorino/ubuntu-cve-tracker:detect_priority_mismatch

One thing we talked about was adding tags that could either be indicators for the priority assessing role, or could be expanded into the explanation itself. A really simple sample of the data store for this could look something like:

diff --git a/meta_lists/priority_explanations.yaml b/meta_lists/priority_explanations.yaml
new file mode 100644
index 00000000000..868d5011dca

+# standardized priority reason text
+# tag/keyword based, so that we can add the tags as part of triage and
+# re-triage to make it easier to generate.
