Send cloud-event to Keptn: Add feature to control evaluation of results

[robertjahn]

Add configuration option to control how the quality gate results are processed.

Here is reference to one way to do this.

• pass_on_warning - a fail keptn result status will stop the pipeline
• fail_on_warning- a fail or warning keptn result status will stop the pipeline
• ignore - will not process the keptn status

Here is reference code that implements this logic https://bitbucket.org/keptn/keptn-quality-gate/src/239ea4a5679a93c06908cf5f9a065aa36a1aa20d/pipe/pipe.sh#lines-91

The WaitFor task now contains two extra fields to control this behavior. "markBuildOnError" and "markBuildOnWarning" with possible values:

• "NOTHING": "as passed - do nothing",
• "WARNING": "as passed with warnings",
• "FAILED": "as failed"
