We can no longer check detected_level as a labels because we now tell loki to categorize our labels, meaning detected_level is not treated as label but a parsed value.
Parsed seems to be similar to structured_metadata but is "metadata" that loki can derive from requests.

Pull Request Details
Add a new integration test for
loki-processthat tests severalloki.processstages against different inputs.I tried to mix different kind of parser and stages and draw inspiration from what we have in our docs. Also all the test fixtures are written when test run so that timestamps are not stale and get to old to be ingested into loki.

Part of: #4953
Notes to the Reviewer
I added the ability to verify structured metedata. For this to work we have to pass a special header to loki:
X-Loki-Response-Encoding-Flags: categorize-labels. This will change the response so I had to update the json parsing logic for it.PR Checklist
