This adds a new Checksum field to the canary webhook body, which is a
hash of the LastAppliedSpec and TrackedConfigs.
This can be used to identify the rollout of a specific configuration,
and differentiate between webhooks being sent for different
configuration and deployment versions.

Add Promoted status condition with the following reasons: Initialized, Progressing, Succeeded, Failed
Usage: `kubectl wait canary/app --for=condition=promoted`
Fix: #184
- halt the canary advancement if pre-rollout hooks are failing
- include the canary status (Succeeded/Failed) in the post-rollout webhook payload
- ignore post-rollout webhook failures
- log pre/post rollout webhook response result
