feat: Load Balancer Implementation for WebRTC Servers

[gabrielmatau79]

Resolve #21 Issue,

This Pull Request introduces the implementation of a load balancer service designed to manage WebRTC servers running mediasoup and includes a significant refactor to restructure the repository as a monorepo. The load balancer optimizes the distribution of room creation requests by tracking server load and maintaining an up-to-date registry of available servers. Key functionalities include server registration, load tracking, and room creation delegation.

1. Server Registration:

• Servers can register themselves via the /register endpoint.

• Data stored for each server:

  • serverId: Unique identifier for the server.
  • url: Base URL of the server.
  • capacity: Maximum number of peers the server can handle.

2. Room Creation Delegation:

• A createRoom method determines the best server (based on current load) and delegates the room creation task.
• The load balancer tracks the load of each server dynamically by calculating rooms / capacity.
  Load Tracking:
