Ignore invalid IPs in X-Forwarded-For when trusted proxies are configured.
What does this MR do?
Catches IPAddr::InvalidAddressError exceptions in
trusted_proxy? when a) a trusted proxy is set up in the gitlab config and b) an invalid IP address is passed to the method (e.g. one with a port attached). When caught, returns
false from the method. Prevents a 500 error in this situation.
