Provide facility to display disk usage statistics including trendline for Confluence site and spaces

Description:-

Currently, the overall disk usage for Confluence is available in the Storage menu under Site Settings. It would be helpful for an administrator if the disk usage for the respective spaces is also available for maintenance activities.

Suggested resolution:-

Provide an option so that the disk usage for individual Confluence spaces is also displayed. In addition, a storage trendline for the Site and Spaces would also be helpful to understand the usage pattern.
