Implement the accounts.OrganizationAccount model

[eronlloyd]

Description

Organization Accounts are the primary container for the platform; users must create or join organizations before being able to do anything else. The platform is mult-tenant, allowing multiple Organizational Accounts to co-exist (and even collaborate, as planned).

Requirements

• Slug field for the organization's "namespace", subdomain, etc.
• All objects created within the namespace must be rooted to the account via an org_account field, whether directly or adjacent to an object that does
• Ownership of child objects should be with the account, not the users that create them
• Settings for the account will likely remain with this model

Dependencies

• None

Tasks

• Write unit tests
• Write functional tests
• Write docstring
• Write code
• Write documentation
