What changed?
Invariants are initialised outside the service and provided as inputs before starting worker service or diagnostics. As a result, the diagnostics workflow is generic and performs the same checks and rootcause across all invariants
Why?
The invariants used in workflow diagnostics were initialised within the service and as a result was hard to setup overrides for alternative implementations of the same invariant
How did you test it?
Unit tests
Potential risks
Invariant interface has been modified so when this PR is merged with alternate implementations within Uber, they need to be modified accordingly
