This commit introduces `DiscoveredPrefixTable` class as a nested type in `RoutingManager`. This class maintains the on-link and route prefixes which are discovered by processing the received Router Advertisement messages. It manages the lifetime of the discovered prefixes (running a timer and removing entries when they expire). It also handles publishing and unpublishing the prefixes in the Thread Network Data as they are added and removed. When there is any change in the table (an entry is added, removed, or modified), it signals this through a callback to `RoutingManager` which can then take action and decide whether or not to re-evaluate the routing policy. A `Tasklet` is used for signalling which ensures that if there are multiple changes within the same flow of execution, the callback is invoked after all the changes are processed. The change in this commit simplifies the overall `RoutingManager` code by abstracting away the prefix table management into its own class and allows us to hide the internal data model used for storing the discovered prefixes.
What is OpenThread?
OpenThread released by Google is... 
...an open-source implementation of the Thread networking protocol. Google Nest has released OpenThread to make the technology used in Nest products more broadly available to developers to accelerate the development of products for the connected home.
...OS and platform agnostic, with a narrow platform abstraction layer and a small memory footprint, making it highly portable. It supports both system-on-chip (SoC) and network co-processor (NCP) designs.
...a Thread Certified Component, implementing all features defined in the Thread 1.2 specification, including all Thread networking layers (IPv6, 6LoWPAN, IEEE 802.15.4 with MAC security, Mesh Link Establishment, Mesh Routing) and device roles, as well as Border Router support.
