This Commit adds: - stream package (provides different implementation of stream producers and consumers) + Redis -> will be used for any non-local deployments + InMemory -> a VERY BASIC implementation that is used for local execution - events package + GenericReporter -> responsible for reporting events, can be used to send any type of event and payload + GenericReader -> responsible for reading events from a stream, can be used to register handlers for any type of event and payload + ReaderFactory -> responsible for launching readers for any type of consumer group&name. - webhook package + The wire frame of the webhook package. - gitrpc/events package + defines event Reader/Reporter for events of category git
