Add a skill for reviewing OpenShift ci results

[rhmdnd]

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.

@xiaojiey @Anna-Koudelkova @taimurhafeez @Vincent056 @yuumasato feel free to give this a try and see if it helps with managing the overall CI for profiles. You should be able to run the script standalone, which could be put into another directory for reuse (it doesn't need to be packed into the same directory as the skill).
