Add VCell Support Role

[Ezequiel-Valencia]

Made it so that if a user can have the VCell Support role, and view any models shared with VCell Support.

Changes:

• DB Driver Policy
• User retrieval functions to return users with their roles
• Builder classes for User Identity and Special User
• Grab VCell supports ID on startup
• A Users roles are passed during communication with clients
• Tests for every change

[Ezequiel-Valencia]

Jim Suggestions:

• Update the startup task to be lazily initialized through local global variable getter
• Use hashmap for user creation instead of assuming the result is ordered by ID
• Include roles in the user DTO, such that a separate special user DTO is not required

I looked at the most recent changes to consolidate into a single User DTO, looks good, approved.
