Access logging

The HTTP connection manager and tcp proxy supports extensible access logging with the following features:

• Any number of access logs per connection manager or tcp proxy.
• Asynchronous IO flushing architecture. Access logging will never block the main network processing threads.
• Customizable access log formats using predefined fields as well as arbitrary HTTP request and response headers.
• Customizable access log filters that allow different types of requests and responses to be written to different access logs.
