Configure the FED and slot numbers as XML attributes
Description
There is an unused feature of xDAQ that allows adding custom attributes to the XML tag describing an application. Such a feature can be used to avoid ordering issues between application instantiations such as in the case of the monitoring suite.
If one doesn't necessarily want to use the XML attributes for all configuration parameters, they can be used to describe the application, both for itself and for the other ones. The FED and slot numbers are good candidates.
Possible fixes
Use XML attributes to specify which FED and slot an application controls, if any. Using a new cmsgemos
-specific namespace is a good idea if possible.
