PollingController.startPollingByNetworkClientId does not type-check the given options #3634
Description
When calling startPollingByNetworkClientId in a controller that inherits from PollingController, it is possible to not pass any options or the wrong options, even if types are supplied for those options in that controller's _executePoll. Since startPollingByNetworkClientId is contained with PollingController, and PollingController has no awareness of what a subclass needs, all it can say is that the options are optional, and if they are supplied, they must be Json. The result of this is that if options are missing from startPollingByNetworkClientId, it can cause errors at runtime, which is not only undesirable because it goes against the purpose of using TypeScript, but also because it it is confusing to consumers.
