Public bug reported:

Frequent calls to Nova's API when displaying the simple tenant usage can
lead to efficiency problems and even crash on the Nova side, especially
when there are a lot of deleted nodes in the database. We are working on
resolving that, but in the mean time, it would be nice to have a way of
disabling the simple tenant usage stats on the Horizon side as a
workaround.

Horizon enabled that option depending on whether it's supported on the
Nova side. In the 2.0 version of API we can simply disable the support
for it on the Nova side, but that won't be possible in version 2.1
anymore, so we need a configuration option on the Horizon side.
