Roles tab is missing in Applications

[ShanChathusanda93]

Describe the issue:
From the roles tab inside the application edit, we can configure the audienace of the roles and we can create/assign application roles to the application as well. Now that is not available in there.

This happened after the fix [1]. This config was validated in the application edit page[2]. This config was introduced for a previous version of the role management we need to come up with a solution for this.

1. Enable the applicationRoles.
2. Introduce a new config and find the references of the applicationRoles and change those configs to the new config to handle the new implementation.

How to reproduce:

1. Go to console and create an app.
2. Go to edit page and the roles tab is not available there.

Expected behavior:

• Roles tab should be available in the application edit.
