The `service.package.artifact` property was missing in the saveState function, so it was not available in the deploy phase.
This PR saves and restores the property correctly, and for AWS additionally sets it during packaging. For AWS the initialization of the property also was missing, possibly due to a merge conflict.
Combination of the following commits:
Re-revert changes for saveServiceState and extendedValidate
Revert most recent changes
Update package artifact to include path and .zip name
Update artifact file path for packaging and name for service state
Update tests for saveServiceState
Do not persist artifacts as it is not needed
Persist package.artifact correctly
