#942 Create DB image when calling POST /image/create

In case the DB entry for an image does not exist when POST /image/create
is called, this patch takes care of calling it.

This adds few optional json parameters to the POST /image/create API. If
optional parameters are included then this patch creates the DB entry,
otherwise it just creates the actual image and updates the existing
entry.

Request:
POST /image/create
