Given that ConnectivityService is moving to a mainline module, we need a @SystemApi for it to listen for changes in blocked status of an uid. So, we decided to create a new API for this which can provide ConnectivityService with more info about why an uid is blocked (which will be useful for adding a new similar onBlockedStatusChanged callback in CM.NetworkCallback) and also captures data saver restriction without having out to track it separately. Currently, NPMS does some redundant computations because we are calculating both uid rules and blocked reasons separately. In a follow-up change, we will compute uid rules using blocked reasons and later possibly remove that onUidRulesChanged callback.
