Rationale
TroubleshooterRoledoesn't grant read permissions in the root. This causes multiple problems, particularly viewing admin queries in the root and interacting with those grids. This change gives the role read permission restricted to the root. More details; https://github.com/LabKey/internal-issues/issues/785Separate, but related, many
SecurityPolicymethods iterate roles in a policy associated with a set of principals, populate roles or permissions into a HashSet, and return the set... only for all callers to immediately convert the set to a stream or simply test for the existence of a single role or permission. Reworking these key methods to return Streams provides convenience and avoids creating, populating, discarding, and garbage collecting unnecessary collections, buckets, etc. in these frequently used code paths. It also allows for short-circuiting in the existence cases, since the iteration process can cease as soon as the desired role or permission is seen.
