Add syslog logs for HTTP requests and responses

This is useful for debuging and getting information on the processes that are
being executed in ogclient.

syslog outputs are something similar to:

Jun 26 10:36:40 ogAdministrator /ogclient: GET refresh HTTP/1.1
Jun 26 10:36:40 ogAdministrator /ogclient: HTTP/1.0 500 Internal Server Err
