provide component provision status endpoint

Currently when an component is being provisioned if no error happens a successful response is sent back to the client (front end or endpoint consumer).

However this successful answer just means that the provisioning app was able to process the request and triggered successfully the corresponding jenkins pipeline.

The whole provisioning process is asynchronous. The provisioning app just place a task in jenkins.

Endpoint consumers miss in this way to get the end result of the quickstarter jenkins pipeline.

To allow further orchestration of provisioning processes in a corporate environment a new endpoint is needed.

In this context, the provisioning app also need to provide an endpoint that could be used to return the status of the quickstarter jenkinsline.

A solution for this is to use the current provision app connection to openshift and query the result of the corresponding triggered pipeline.
