As a tenant Admin I want the ability to customize the in-app display name for user types.

[nopivnick]

e.g., the mc tenant schema should include a map with field name permissionLabels with the following values:

permissionLabels
  user : "User"
  worker : "PA"
  reviewer : "Liaison"
  services : "Services"
  admin : "Admin"

similarly, the itp tenant schema should include:

permissionLabels
  user : "User"
  worker : "ER"
  reviewer : "1st Approver"
  services : "Services"
  admin : "Admin"
