These authorizers authorize the caller as a downstream or admin workload by looking up the registration entries matching the caller ID.
They attach the respective downstream or admin entries to the context.
These authorizers use a helper to obtain the entries for the caller that uses the context to cache retrieved entries. This prevents the entry lookup from happening more than once if these authorizers are used for the same RPC (e.g., via AuthorizeAnyOf).
