| r"""Instance class. |
| |
| Define the instance class used to hold details about an AVD instance. |
| |
| The instance class will hold details about AVD instances (remote/local) used to |
| enable users to understand what instances they've created. This will be leveraged |
| for the list, delete, and reconnect commands. |
| |
| The details include: |
| - instance name (for remote instances) |
| - creation date/instance duration |
| - instance image details (branch/target/build id) |
| - and more! |
