Provide the ability to run several instance of an analyzer on the same machine. This require that theses sensors are identified by a user defined name (this name is not customizable currently), so that a sensor instance get it's own analyzerid.

Additionally, this option need to be handled prior to any other option which might depend on this one, which will require for better support of option priority handling with prelude-getopt.c
