A large portion of the handler logic within the prometheus exporter file exporter.q is generally useful for many use cases but one or more handlers may need to be overwritten by a user prior to initialisation.
This PR provides a command line option for noinit which if defined will suppress the execution of .prom.init[] at the end of the exporter.q file allowing users to load other files/define logic they want to introduce before the handlers will process messages according to the prometheus exporters logic
