std::unordered_map< int32_t, ClientInfo * >	mClientRepo
	Maintains Client Info indexed by PID.

std::unordered_map< int32_t, ClientTidData * >	mClientTidRepo
	Maintains Client Info indexed by TID.

Detailed Description

Stores and Maintains Client Tracking Data for all the Active Clients (i.e. clients with outstanding Requests). The Data Tracked for each Client includes:

PID, and the Access Level Permissions (Third Party or System) for the Client
List of Threads Belonging to the PID
List of Requests (identified by Handle) belonging to this Client
Health and Timestamp of Last Request (Used by RateLimiter)
Essentially ClientDataManager is a central storage for Client Data, and other Components like RateLimiter, PulseMonitor and RequestManager are clients of the ClientDataManager.
