There was a problem hiding this comment.
This will likely show up in Grafana, let's try:
"Invalid request %s. This query has been identified as one that destabilizes our system. Contact your system administrator for more information"

What this PR does:
It provides a mechanism to refuse requests based on a regex blacklist. A new middleware was created and executed the first in the query pipeline. Any request that matches will return a 400 status code response.
Due to the way we build the pipeline I decided to make the new middleware as an AsyncMiddleware, that way it can be executed first in the chain. We should explore the possibility of having just one type of middleware so that they can run in any order regardless of their work.
Which issue(s) this PR fixes:
Fixes #3769
