We run periodic CI jobs every week for OpenShift/RHCOS compliance
content. This commit adds a skill and script to parse the latest CI
results from Prow and builds a compliance report from them.

The idea is that we can use this to help keep the assertion files
up-to-date in the project by reducing the overall hops required to get
to the most recent CI runs and checking the results.

The fetch_results.py script can actually be used standalone, which is
useful for assessing gaps in testing coverage, or changing rules. But,
it can also be fed into the skill so that an agent can help diagnose
rules that have been refactored recently, and help update assertion
files.
