Introduce failure mechanism for WorkloadDeployment phase

[odubajDT]

Description

In pre/post-deploment task or evaluation phases as well as promotion phase we have a failure mechanism to fail the phase either after certain amount of retries or after a timeout. We should be implement similar functionality for the WorkloadDeployment phase.

Details

We should introduce .status.DeploymentStartTime into KeptnWorkloadVersion CRD. Afterwards we should adapt the logic of KeptnWorkloadVersionRecolciler to set the .status.DeploymentStartTime and periodically check that the current time is not beyond the start time + timeout.

The value of the timeout will be set by a new parameter in KeptnConfig

A small PoC is available here.

DoD

• KeptnConfig has a new parameter for DeploymentTimeout
• the parameter of KeptnConfig is reconciled by KeptnConfigReconciler
• new parameter KeptnWorkloadVersion are introduced
• KeptnWorkloadVersionRecolciler is adapted
• unit tests
• integration tests
• new functionality is documented

Note

Please try to provide the implementation in multiple small PRs and not a single big PR
