Enrich Deployment EVent sent to Dynatrace with Labels & Source

[grabnerandi]

If an external tool, e.g: Jenkins, GItLabs Pipelines ... is doing the deployment and sends a deployment-finished event to Keptn it typically enriches it with e.g: Pipeline URL, GitCommit, ... by passing these values as labels

Users have asked to promote these labels to the corresponding Dynatrace Deployment EVent.
Therefore we suggest to look at all incomgin labels and re-use them for the sent deployment event to dynatrace. For labels such as deploymentName, deploymentVersion, ciBackLink, remediationAction the Dynatrace SErvice should forward them as exactly these propoerties. For all other labels just pass them as customProperties

sample - incoming keptn depoyment event

{
  data {
    labels: {
      "ciBackLink" : "mypipelinlink",
      "gitcommit" : "abcafawdfa"
   }     
...
}

that would translate into a Dynatrace Event like this

{
  "eventType": "CUSTOM_DEPLOYMENT",
  
  "ciBackLink":"bridge.keptn.mykeptn/context",
  "customProperties":{
    "ciBackLink":"mypipelinlink",
    "Git commit": "abcdef"
  }
}

This enhancement in combination with #115 gives our users full flexibility
