plugin manhole: manhole debug plugin, first draft: this plugin open a telnet server which open a Python interpreter and allows to inspect the backend while it is running. To enable it, the settings "manhole_debug_dangerous_port_int" must be set to the desired TCP port in [DEFAULT] section of sat.conf. A warning will be logged if the server is enabled. Currently only a telnet server is available, and no login is required. This may change in the futur to enable login/password and ssh access, or even an XMPP access. This is a debugging feature and must only be used during development. Once in the Python interpreter, the "host" variable is accessible.
