This PR solves a parsing error when trustAnyForwardedAddress is enabled. This is caused by the X-Forwarded-For header containing an IP address, and not a host+port. This causes the split to fail with missing port in address or too many colons in address, leading in the feature not actually working.

Additionally, I've included two minor enhancements in the logging:

  • Add resolved remote address/host to log entries.
  • Add the subject that is rate limited to the logged entry.

Solve a parsing error when `trustAnyForwardedAddress` is enabled.
This is caused by the `X-Forwarded-For` header containing an IP address,
and not a host+port.
The current logs contain only the original host and remote address.
This makes it difficult to see who actually performed the request without correlating other logs.

Add these values to the log context in addition to the original values.
Add the subject that is rate limited to the logged entry.
