Description

Improve network actions to expose connectedPeers and disconnectedPeers

Motivation

Right now we expose getPeers and getUniqueOutboundPeers
getPeers action returns a list of all the peers with state value 0 for disconnected and 1 for connected peers but other modules usually are interested in connectedPeers and we want to get rid of state value in the future.

Also, there was an extra overhead every time we call these actions as it was going through consolidatePeers function that is used to assign state value based on connection state of peers.

Acceptance Criteria

Other modules should be able to call connectedPeer or disconnectedPeers actions without passing state filter.
