Description

The OpenAPI 2.0 (Swagger) specification allows for the description to be present in the security definitions. When we present the choice to the user to select one security definition based on which the authentication related properties will be configured for the new custom API connector we only display the kind (Basic Authentication, OAuth, API Key) we don't display that description, if present.

We should also display the description to make it easier for the user to pick the security definition/authentication method for the new custom API connector.
