Create storage informational pages

[markmhendrickson]

This entails creating pages that display information about how the app backs up data to particular storages. These pages can be used to inform and attract visitors who have interests in these storages by explaining how we support them before the visitor signs up.

These pages can be designed to receive traffic from other points of entry in the app or linking from elsewhere such as search engine results.

The design for these pages may hew closely to those for sources.
