Fix _newPeers and _triedPeers to match the LIP

[jondubois]

Expected behavior

Scope

The goal of this issue is to make sure that the _newPeers and _triedPeers (address book) does not grow to unlimited size. This should be done according to the LIP.

• This issue is partly related to buckets because buckets will naturally restrict the size of this list: https://github.com/LiskHQ/lisk-sdk/issues/3334
• We still need to consider the size of each PeerInfo within the lists.
• This issue also involves making sure that peers are moved between the two lists according to the LIP.

Description

This is related to https://github.com/LiskHQ/lisk-elements/issues/1072 - The _newPeers and _triedPeers maps (which store P2PDiscoveredPeerInfo) need to have a size limit to prevent DoS. The LIP has a mechanism which limits the size of the _newPeers and _triedPeers maps so it should be implemented.

Actual behavior

_newPeers and _triedPeers are not currently managed according to the LIP.

This issue is there to address any remaining details which may be left over in order to fully comply with the LIP regarding the management of the the address book (_newPeers and _triedPeers).
