harness

[arttor]

Draft PR. Main idea here is to configure agent harness to be able to fully automate dashboard enpoint implementaion with AI.

Harness:

• parity test: mechanical check to call old dashboard api and new ceph-api with the same http request and compare that responses are the same
• check that all implemented endpoins covered by parity test
• updated linter, test-containers, dependencies, and all CI/CD best-practices from https://github.com/clyso/chorus

status:

• parity test and coverate implemented
• non matching endpoints or response fields have to be explictly listed in api_diff.yaml to pass CI

TODO:

• review/cleanup
• make CI pass for all existing ednpoints with no ignore entries in api_diff.yaml
• configure planning/impl/review agents for autonomuos endpoint implementaion
