Option tracker registration and deregistration services.
This is a service that will allow registering an option. Each option has a name. The name is UTF8mb4 and is unique in the list. Manipulating the option list is an "expesive" operation since there is a global lock involved.
Each code container (a component or a plugin) should register its options during its initialization and should unregister them during its deinitialization.
