Update the AccessLog pattern to show more

The existing pattern doesn't show the IP address of the original requester.
This change adds a value of '%{org.apache.catalina.AccessLog.RemoteAddr}r' to
show the IP address of the original requester as provided by the RemoteIpValve.
'%a' will continue to show the IP address of the Router.
