6196f69f4d Create New Job when Canary's Interval changes 
- Currently whenever the Canary analysis interval changes, flagger does
not reflect this into canary's job.
- This change will make sure the canary analysis interval got updated whenever
the Canary object's interval changes

29cdd43288 Implement skip analysis
