function used to get the list of SDMXServiceProvider known by rsdmx (hence known by readSDMX to query data or metadata in an easier way). This function can be easily used to interrogate the list of known providers, and eventually consider adding one at runtime with addSDMXServiceProvider
getSDMXServiceProviders()
an object of class "list" (of SDMXServiceProvider)
