	**[TECHDEBT] AddrBook management optimization and refactoring** [#246](github.com/pokt-network/pocket/issues/246)
	- Added `peersManager` and `target` in order to abstract away and eliminate redundant computations
	- Refactored debug logging in `getTarget` to print first and second target on the same line
	- Refactored `AddPeerToAddrBook` to use an event-driven approach in order to leverage sorted data structures
	- Added `RemovePeerToAddrBook` making use of the same pattern
