Add quick-connect command for optimal server selection

[parfenovvs]

Summary

Implement mbvpn quick-connect command that automatically selects and connects to the optimal server based on user's location and server performance.

Features

Intelligent Server Selection

• Automatic geo-location detection
• Server performance analysis (latency, load)
• User preference learning
• Fallback options for server failures

Command Options

# Quick connect to best server
mbvpn quick-connect

# Quick connect with preferences
mbvpn quick-connect --country US
mbvpn quick-connect --city "New York"
mbvpn quick-connect --protocol udp

# Show selection criteria without connecting
mbvpn quick-connect --dry-run

Selection Algorithm

1. Location-based filtering

   • Detect user's approximate location
   • Filter servers by distance/region

2. Performance testing

   • Ping test to candidate servers
   • Load balancing consideration
   • Historical performance data

3. User preferences

   • Remember previous successful connections
   • Respect configured preferences
   • Learn from user behavior
