This commit provides the implementation of functionality that blocks sms/calls notifications on home screen when tethering is active. Previously, the notifications could be visible if the notifications were visible prior to tethering activation. By the design, the functionality should not clear the notifications, just temporary hide them. That is achieved by implementation ot the functionality in NotificationModel which is an UI presenter.

The NotificationProvider is responsible for creating and managing Notifications. Each Notification represents a unique
event and thus at most single object (of a respective type) can be stored in the provider. The provider's structure is shown on following diagram:
Model-View structure
NotificationsModel is responsible for creating and decorating NotificationListItems based on NotificationsChangedParams received.
The model serves also as a local provider for gui::ListView.
