Assigning roles/teams in Proof workflow stages

[#1]

Description - - In Proof HQ, when creating Workflow templates it should allow us to add roles or teams that exist in Workfront.

Why is this feature important - It reduces the need to maintain workflows in proof HQ and enhances the usage of proofing workflow templates

How would you like the feature to work - When creating workflow templates in Proof HQ. While creating a stage and adding people to those stages, it should allow the user to not just select individual users but also allow them to select teams or roles from the respective Workfront instance.

Current Behaviour - Proof HQ only allows the user to add individual users to stages when creating workflow templates in Proof HQ.
