While working on MDL-83906, it was noted that the current "Include authentication details with the backpack" setting is not used in the Open Badges v2.0 specification. This issue is to remove this setting to simplify the user interface, avoid confusion and reduce the complexity of the codebase.

Things to consider include:

• Removing the "Include authentication details with the backpack" setting from the form and any related code.
• Removing the "Testing backpack connection" feature (from the Manage backpacks page), as it won't be required anymore because there won't be any authentication details to test.
• Updating any documentation to reflect the changes made.
