Add an option to disable inbound rate limiter (#4327)

Browse Source 
## Issue Addressed

On deneb devnetv5, lighthouse keeps rate limiting peers which makes it harder to bootstrap new nodes as there are very few peers in the network. This PR adds an option to disable the inbound rate limiter for testnets.

Added an option to configure inbound rate limits as well.
