Tabs in launch server wizard not depending on OPENSTACK_NOVA_EXTENSIONS_BLACKLIST

OPENSTACK_NOVA_EXTENSIONS_BLACKLIST is used to disable specific extension.
In the launch instance wizard, by example the Server Group tab should be hidden
when the extension "ServerGroups" is blacklisted but it isn't.

It could be interesting to make these tabs dependent of the supported extensions.
