Refactor set deployment status endpoint

The current endpoint for updating the status(active/paused/terminated) for a deployment is a PUT request to /deployments/by/status/

{status}

with the merchant id in the body of the request.

This feels a bit odd.

This should be changed to be a put to /deployments/

{merchantUuid}

/status so the deployment for a merchant is treated like a resource and we are just modifying that resource. The status value could continue to be passed in the body of the request or as a path parameter.

The /

{object}

/by/

{fieldname}

/

{fieldvalue}

url scheme is used for filtering objects by their values because it reads very naturally for that purpose and the results of such a query is not a real resource.
