Create security group button gone

[Sam Morrison]

We upgraded our dashboard to juno and now the "Create Security Group" button has disappeared.

I've tracked this down to a key error in class CreateGroup(tables.LinkAction) method allowed:

if usages['security_groups']['available'] <= 0:

KeyError: ('available',)

pp usages['security_groups']
{'quota': 10}

Should say we're using nova security groups

When using neutron I don't see it either.

Cannot reproduce on master branch

I think this is duplicate, let me know if you think otherwise.

I'll propose a backport to Juno as well.
