feat(network): permanent peer store

[kehiy]

Description

This PR adds a permanent json-based peer store. It keeps a backup of all connected peers at runtime when we turn the node off and restore/use it when we try to start our node again.

This change will enhance the syncing process. here is a part of peers.json after my test for a few second:

I suggest you guys test it on your side with your environment to ensure it works properly.

• Fixes Keeping peer list when node goes off #866

[kehiy]

Three additional notes:

1. The peers.json can be shared offline same as offline chain data download for better syncing. (for example, I'm running a new node so I can use the previous node peer store to have more seed nodes to connect to.)

2. We can add a disable option for this peer store in the config but I thought it was unnecessary.

3. offline nodes, private IPs, etc will be ignored, and checking them or removing them from the peer manager and saving the store then is not very efficient or helpful. (simply won't make anything worse or better that affects the health status of the node, if you think it does, please add details.)
