Every droplet comes with X terabytes of transfer.

If one droplet goes over its allocation, it is charged for more bandwidth utilization - even if every other droplet in a Project (or Team, or User, etc) is under its allocation threshold.

At the least, all droplets in a given Project should be able to share their total allocated bandwidth (eg 5 1TB droplets should be able to use 5TB total - not merely 1TB/droplet).

Furthermore, I should be able to make arbitrary bandwidth pools (by Team, Project, manually-selecting a subset of droplets, etc) that would aggregate otherwise-individual bandwidth thresholds
