Chef Server should allow creation and association of Organization

[kalroy]

Chef Server API requires pivotal key to create and associate a user to an organization.

The API should allow server-admins to do the same operations as pivotal users.
This will avoid the need to distribute the Pivotal key for users.

@kalroy could you please add some more context around why this change is required. Thanks!

@PrajaktaPurohit this would be so that a tool such as Terraform could be used to manage users as code. I have extended the Terraform provider with many resources, however associating a user with an organization still requires the pivotal PEM.

I feel that a user with admin privileges should also be able to perform this action.
