Need a force function for undeploy (to keep going on error)

Goal: Improve rollback on failed installation, and do not fail on underdeploy if object doesn’t exist due to install failure

Scenario: In trying to automate wskdeploy Dan Krook found that undeploy hits an error and stops processing leaving server in unknown state. In one example he sent to me...

He deployed a manifest where

a dependent kafka Package did not exist
so its Trigger not created
therefore its associated Rule was not created

undeploy tries to delete Rule (does not exist) and Errors out and stops trying to undeploy at that point

Manifest: https://github.com/IBM/ibm-cloud-functions-refarch-data-processing-message-hub/blob/master/runtimes/nodejs/manifest.yaml

packages:
    data-processing-message-hub:
        actions:
            # Action named "receive-consume"
            # Creating action as a regular Node.js action
            receive-consume:
                function: actions/receive-consume.js
            # Action named "transform-produce"
            transform-produce:
                function: actions/transform-produce.js
                inputs:
                    topic: $DEST_TOPIC
                    kafka: $KAFKA_INSTANCE
        sequences:
            # Sequence named "message-processing-sequence"
            # Creating the sequence that links the get and post actions
            message-processing-sequence:
                actions: receive-consume, transform-produce
        triggers:
            # Creating the message-trigger trigger"
            message-trigger:
                feed: Bluemix_${KAFKA_INSTANCE}_Credentials-1/messageHubFeed
                inputs:
                    isJSONData: true
                    topic: $SRC_TOPIC
        rules:
            # Rule named "message-rule"
            # Creating the rule that links the trigger to the sequence
            message-rule:
                trigger: message-trigger
                action: message-processing-sequence

output:
