Utilization: Silo usage overview

[benjaminleonard]

Presently an operator can pick a silo and check its utilization using the listbox. We'd like a tabular breakdown of usage so that an operator can compare and check utilization across all silos at a glance.

These designs are out of date, but structurally this is what we're looking for:

The same component can be used at a silo level to view utilization across projects.

Presently the API does not give us this information in a single response, but we can stub this out by batching the queries and replace them when that's available.

Aiming to get that initial version done for the next release (3).
