Added directory for each example and individual files of code

I thought it would be easier to follow the examples if the code in the markdown pages were broken out into their own files.

There are some issues with the link, check this for instance

There's definitely something weird going on. When I click on the link you pasted I get a 404, but these steps pull up the page: [Scenario 1] Step 1: Click on the link you posted and get 404 Step 2: With same link in address bar, delete the markdown file extension '.md' and the page comes up

[Scenario 2] Step 1: Go to the folder the file is in: https://github.com/brotheraaron/oci-learning/tree/master/terraform/OKEClusterUsingTerraform Step 2: Click on the markdown file and the website comes up with the markdown file extension: https://github.com/brotheraaron/oci-learning/blob/master/terraform/OKEClusterUsingTerraform/OKEClusterUsingTerraform.md

I'll do some googling and get back to you.
