[Feature Request] Support for multiple proxy pools and ports in a single instance

[yudinikita]

Currently, rota supports a single proxy pool and one listening port per instance. To use different proxy sets for different applications (e.g., Application A needs residential proxies, while Application B needs datacenter ones), users must deploy multiple separate instances or Docker containers.

Proposed Solution

Add the ability to define multiple "pools" within the configuration file. Each pool should be able to:

1. Listen on a specific port.
2. Use a specific proxy source file/list.
3. Have its own rotation strategy

Example configuration concept:

pools:
  - name: "app_one_pool"
    port: 8001
    source: "./proxies_fast.txt"
    strategy: "round-robin"
  
  - name: "app_two_pool"
    port: 8002
    source: "./proxies_cheap.txt"
    strategy: "random"

Why this is needed?

• Running a single Go binary is more efficient than managing dozens of separate containers for large-scale setups.
• It allows users to separate traffic for different target websites with different rate limits.
• Managing one configuration file is easier than maintaining multiple deployment scripts.

This feature would make rota much more powerful for developers who need to manage complex scraping infrastructures.

Hey @yudinikita! This feature request is exactly what we implemented in PR #27.

PR #27 adds:

• Named proxy pools — each pool has its own geo filters, rotation strategy (roundrobin/random/sticky), health check URL and cron schedule
• Per-user routing — each user has a main pool + ordered fallback pools
• Auto-sync — pools are rebuilt automatically after every proxy source fetch
• Async health checks — with real-time progress bar
• Dashboard pages for managing sources, pools and users

All through a single instance with a TimescaleDB backend (no multiple ports per pool — instead users authenticate to port :8000 and are routed to their assigned pool automatically).

Would love feedback if you get a chance to test it! PR: #27
