Description

The Roles interface now is kind of messy, because it has a DB-specific function:

public ImmutableSet<String> getRoles(@Nullable String database, String group, Boolean isURI);

It makes more sense to just have a Roles class that store roles, and have the PolicyEngine do the service-specific calculations.
