Added

• Configurable routing timeouts: new options RAINBOW_HTTP_ROUTERS_TIMEOUT and RAINBOW_ROUTING_TIMEOUT (and the similar command-line flags) allow setting timeouts for routing operations. The former does it for delegated http routing requests. The latter specifies a timeout for routing requests.
• Added BITSWAP_ENABLE_DUPLICATE_BLOCK_STATS: Controls whether bitswap duplicate block statistics are collected. This is disabled by default since it has a performance impact.
• Allow specifying a DNSLink safelist: RAINBOW_DNSLINK_GATEWAY_DOMAINS defines which dnslink domains are allowed to use this gateway.
• Added reverse proxy documentation with Host header forwarding requirements for subdomain gateways behind nginx (#317).
