#### Why I did it

Enhance yang model for networking-metadata.

Adding a new field in device metadata YANG model to distinguish the management type of the device. Depends on the users, this field can be used to tell the purpose of deployment or who/how the device is being managed.

##### Work item tracking
- Microsoft ADO **(number only)**:

#### How I did it

This change adds a new field called mgmt_type for this purpose.

#### How to verify it
