Add an "Estimated Zero Credit Date" to AGOL Organization Overview

[ColinLindeman1]

As an administrator of an ArcGIS Online Organization I want to know at a glance when I will run out of Credits so that I can acquire more before they run out.

The AGOL Organization Overview has a Credit section that shows the total remaining credits and the usage for the last 30 days and last 24 hours. It would be helpful to have another metric that shows the estimated day the organization would reach 0 total remaining credits. This metric should take into account when certain credits are set to expire (as described: Additional credits are available for purchase in blocks of 1,000 and are valid for 24 months before ...).

To add to this idea, it would also be extremely useful to have an "Estimated Daily Credits Consumption" field in the "My Content" pane, showing up on each row next to the layer, app, etc., which would be sortable and allow users to see how many credits each of their files are consuming daily.  It could be used as a tool to prioritize file cleanup and understand how the credits are being consumed throughout the files within the organization.  This could be especially helpful in providing perspective for large hosted feature layers with lots of attachments, as it is difficult to estimate the credit consumption for those types of files.
