[Tracker] Rate limiting

[bkolad]

Description

The goal of this workstream is to introduce a custom rate-limiting mechanism based on IP and CredentialId Access to the following resources should be limited:

• tx_exec_time
• tx_size
• tps
• gas_used

Checklist

• Pass SocketAddr from axum handler to process_accept_tx Rate limiting: pass SocketAddr from Axum to process_accept_tx. #2170
• Adjust the above logic to work with nginx
• We need to apply rate limiting to failed transactions too. For unsuccessful transactions, pass both apply_tx_to_in_progress_batch_inner and gas_used into apply_tx_to_in_progress_batch_inner. https://github.com/Sovereign-Labs/sovereign-sdk/pull/2172/files
• Implement RateLimiter service that rate limits based on IP & CredentialId.
• Add handling for x-forwarded-for header Rate Limiting: Add handling for x-forwarded-for #2199
• Add config that respects cutom limits: Rate Limiting: Add SovRateLimiterConfig and Runtime::resolve_address #2230
• Add custom limits for special CredentialId & IP Rate Limiting: Add SovRateLimiterConfig and Runtime::resolve_address #2230
• Add relevant metrics Rate Limiter: Limit number of concurrent users. #2241
• Test everything on AWS and specifically verify IP-based rate limiting.
• Enable the service in the dev branch
