[Tracking] Lifecycle Controller can be injected in manifests

[thisthat]

Goal

When a Kubernetes Manifest is applied, the Keptn Scheduler is injected for pods that are correctly annotated and Kubernetes Events for Pre-Deployment are available in the K8s Event stream.

Technical Details

A Kubernetes Manifest, which is annotated with Service and Application Name, gets applied to the Kubernetes Cluster.
Afterward, the Keptn Scheduler gets injected (via Mutating Webhook), and Kubernetes Events for Pre-Deployment are sent to the event stream.
In this step, the Scheduler only creates events, and no further actions are taken.

User flow

1. Apply Deployment manifest annotated with keptn-service and version
2. Watch the event stream of the created service resource via kubectl describe keptnservice ...

DoD

The start and end of pre-deployment are shown in the K8s event stream.
