Add admin and orgs

Add recipes for creating admin users and creating organizations.

Borrowed functionality from @misheska at https://github.com/misheska-cookbooks/chef-server12

Would like to combine the functionality provided by these two cookbooks into one chef-server cookbook to rule them all. 
I agree and right now this doesn't even work on the first Chef converge. Seems like the install is still doing it's reconfigure (delayed) when it hits this code. On a second Chef converge the user and org is created.
