'''
Create several different app profiles and contracts. Built to create a demo
environement that based on the names and descriptions given below.
This script required modifications that I have added to the acitoolkit.
These modifications allow the addition of a stateful filter on a contract.
As of Jan 10th I have made a pull request for branch:
https://github.com/datacenter/acitoolkit/tree/Add-stateful-to-FilterEntry
If you get the following error, that is the problem:
TypeError: __init__() got an unexpected keyword argument 'stateful'
The above pull request was merged into the acitoolkit. If you get the above error
you need to get the latest version of the toolkit and install it.
Usage: create_complex_tenant.py tenant vmmDomain
tenant and vmmDomain are optional. Tenant can be used alone, vmmDomain must be used with Tenant.
