✨ Controlplane checkpoint relay

[Meshiest]

✨ Feature

The controlplane should allow agents to upload and download checkpoints from eachother

Motivation

With the features provided by #182, #183, and #181, would allow agents to rewind based on checkpoints provided by alternative locations (agent-to-agent, cdn-to-agent, controlplane-to-agent)

1. User finds a checkpoint on an agent for a given height
2. Controlplane requests agent to upload the checkpoint (Or the user uploads a controlplane)
3. Another agent (or user) can download the checkpoint from the controlplane

Implementation

Could be implemented in one of these ways:

• The controlplane is a relay or CDN and stores the checkpoints
• The agents P2P download checkpoints from eachother using the controlplane as a wireguard or STUN/TURN/libp2p relay
