Investigate adding a "Use Console" option for Device Code Credential

[ramya-rao-a]

@jonathandturner Can you add details as to what exactly is required here?

Here's from Vinay:

Functionality/Feature Request:
We need to add the functionality which provides user the ability to indicate that Device Code Credential should send/print the device code info details to the console.
All the languages should've an issue around this in their October Milestone for Identity.

Approach:
So, to achieve this, the approach which we are going to take is to print the device code details to console as the default behavior. It will be overridden by the user if they configure their custom callback during Device Code Credential construction.

Next Steps:
Currently, callback is a required parameter for Device Code Credential.
We need to make it optional and default the callback to print to console.
