Allow more then 48 hrs history to be graphed in the VirtServer UI
In the Statistics view of a deployed Virtual Service in the VirtServer Web Console, there is an historical graph of received traffic, with a 24 and 48 hour option. We need to be able to look at a longer history for the service and would like a '1 week', '2 week', '1 month' and 'lifetime' view of the historical data if possible. Looking at the underlying VirtServer api, the v1.2/statistics/<deploymentID> call has at least 2 weeks of data provided the service has been running that long, so it would seem to only be a matter of adding additional entries into the Dropdown to query for the appropriate time ranges and rescaling the graph.
