Developer Core Concepts

[djwfyi]

Add a Developer Core Concepts page to parallel the similar docs that we have for Administrators and Operators.

Review the basic operations:

• PUT
• GET
• HEAD
• LIST
• DELETE

[djwfyi]

Go, Python, and a third language either C# or Java/Node.

On DELETE, cover #741 request as well.

Start by breaking this into subtasks.

Proposed plan:

• Test/update existing Quickstart pages (located in the SDK repos and included in docs via automation). Update SDK quickstart pages #1042
• Tutorials with sample code illustrating the same basic operations for each SDK. (TBD if these should be in addition to Quickstarts or replace them.)
• Update current SDK main page to cover concepts and link to individual SDK tutorials.

Likely order of operations:

1. New content for Go, Python, and perhaps Java.
2. Update main SDK page.
3. Continue updates for remaining languages.

Sticking this back in To do for the moment. SDK updates are taking a bit.
