Currently if there is an canary analysis underway and a new revision is applied on the cluster, Flagger will wait for the new revision to be rolled out and will resume the analysis. This could lead to an erroneous promotion since the new revision will not be fully validated. Instead of resuming the analysis Flagger should reset the validation process (set the failed checks and canary weight to zero) and start a fresh analysis.

Fix #30
