Restore the "Show Terminated" link on the Usage reports

[Julie Pichon]

The Usage tables used to have an option for also showing Terminated instances that were active during the selected time period. The backend code to do this is still there (you can verify this by navigating to /project/?show_terminated=True manually) but it would appear we lost the link.

You can see an example of how it used to be in the templates here: https://github.com/openstack/horizon/commit/64b81acc0a98a3e8a5cee834d206c443098a012b

We need to verify if it's still actual.
