Enable client address in Horizon's logs.

Horizon's backends (httpd) see IP address of the haproxy in the logs instead
of the client address.
This patch allows to:
  - Install the remoteip httpd module [1].
  - Use the X-Forwarded-For HTTP header and override the haproxy address.
  - Configure the Horizon's logs with the client address via httpd logformat.
