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. 
Do we need \'s on each line?

Though I'm not sure if this is is any easier to read/reason about than just using a long string?
