Make PUT /dashboardconfiguration restore default settings when called with no request payload

[long-sean]

Prerequisites

• I have searched open and closed issues to make sure it isn't already requested
• I have discussed this in #feature-discussion or #backlog and the consensus is that this is something we plan on adding in the near future
• I have written a descriptive issue title
• I have linked the original source of this feature request
• I have labelled the value stream (area/core, area/steps, ...)
• I have added the kind/enhancement label

The enhancement

Change the PUT /dashboardconfiguration response contract by not returning an error message for requests without a payload/body

What is the problem this solves or benefit it gives

• More consistent endpoint behaviour
• Default settings can be restored by a request with an empty request body

Proposed solution

The current validation which returns a "No request body" error message will not be ported over to ASP when this endpoint is converted during project-nancyfx-migration
