[Feature Request] Scope timeline to errors only

[dinoilic]

This is in reference to #443

Summary

Currently the tool that fetches the timeline of a given build is being worked on, which will be super helpful. However, some builds can yield a huge JSON response in the timeline API.

Tools

I would love to have a tool that can get the timeline, but filter it down to only those events that yielded errors. This would help developers ask questions like:

"In this PR: <PR link>, get the latest build errors and summarize what needs to be done to fix them".

build_get_timeline_with_errors_only: Fetch a build timeline and scope it down to errors only. There's a property called errorCount that can potentially be filtered on.

I'm open to any suggestions here though, if there's a better way to scope down to the errors a certain build produced, that would also be great.

@nikolapeja6 couldn't we just add a param to scope it down to errors only instead of doing a seperate tool?
