/**
 * Main Function
 * @since 1.0.0
 * @example
 * This is the basics on how to use this plugin:
 * ```js
 * app.register(fastifyRabbit, {
 *  connection: 'amqp://guest:guest@localhost'
 * })
 * ```
 * This will allow you to read from your Fastify "object" and
 * use this plugin at the "rabbitmq" level. From there you can execute and maintain
 * the RabbitMQ Connection using the 'rabbitmq-client' package, which is wrapping around
 * this plugin to execute functions it provides.
 *
