Description

Currently, in a multi-tenant cluster FairCallQueue Identity is limited to UserIdentityProvider. Tenants tend to get passed burst RPC loads by using different service ID. This Jira requests that GroupIdentityProvider and MappedUserIdentityProvider be implemented to allow better tenant experience for clusters with multiple tenants.
