Public bug reported:
Currently, Horizon does have a blacklist for Nova extension to skip some
features of Nova which can be used by cloud operators.
However, on the Instance panel, there are 5 actions need to call the
extension_supported function to check if the feature/extension is
supported or not. Though it's cached, it's still taking about 2ms * 5
actions * 20 instances = 0.2 second. So it would be nice if we can have
a white list for supported/known extensions to save the 0.2 second.
