Description

Currently the Composer has an option of showing the JSON representation of a descriptor that's being created/edited. Now that we support YAML format for descriptors, the JSON viewer will be converted to a YAML viewer as YAML is more human-friendly. This will be offered as a purely front-end feature with no support from the SO.

Demo or definition of done

Demonstrate the following:

1. A user should be able to view the YAML format of a descriptor that was onboarded using the Catalog Manager.
2. A user should be able to view the YAML format of a descriptor that he/she has created using the Composer.
3. A user should be able to view the YAML format of a descriptor that he/she is editing, irrespective of whether the original descriptor was onboarded using the catalog manager or created using the Composer.
