feat: local discovery

[danisharora099]

Problem

Whenever a js-waku node is started, it bootstraps itself into the network using a static multiaddr passed by the user, or by using default fleets. These nodes are then used to discovery more nodes using Peer Exchange.

Solution

This PR introduces the usage of Local Storage as a discovery layer that can be used to store & fetch peer information (peerId and multiaddr) of healthy peers that js-waku was previously able to connect to, for that particular app & user.

This reduces the amount of time to discovery healthy nodes by storing previously known healthy nodes to be stored in the Local Storage which can be used as a way to bootstrap your way into the network without relying on the bootstrap fleets, thus also reducing load on them while increasing decentralization.

Notes

• makes the LocalStorageDiscovery part of defaultBootstrap option
• Addresses TODO2 on feat: SDK for redundant usage of filter/lightpush #1463 -- setting up usage of redundant nodes for Light Push & Filter.

Does this interface need to be updated as well? https://github.com/waku-org/js-waku/pull/1811/files#diff-7a99f40b2c8bda03c8c1333fd225faef1127292ec63c8af55aecfeeac1c1dc31L39-L46
