Provide accounting for image & project allowance usage

Currently there is no way to audit the consumption of our image and project allowances in Pix4Dcloud. We can only see the current number consumed for each. In order to properly track and budget our usage, we need to be able to see usage over time as well as filtered by project, user, etc. We need to be able to see trends in our usage, not just an instantaneous balance. Other cloud platforms such as ArcGIS Online offer this functionality. Please add it to Pix4Dcloud.
