This version contains the following pages:

- Overview displays charts/reports (Currently only placeholders)
 - Configurations allows to define new backup configurations and link them to
   instances
 - Backups shows a list of all succesful backups and allows to restore them
 - Restores shows a history of all restored backups

It communicates with the api server via the client apis (freeezer.client.client).
The "glue code" between client apis and the UI lives in freezer.api.api.

Implements: Blueprint freezer-api-web-ui
