🚀 Feature Proposal

It would be good to support customAttributeKeys as pino-http does. Currently there is no elegant way to change for example req key to httpRequest

Motivation

Google cloud log entry has own logging structure, including httpRequest. By adding custom attribute key req: 'httpRequest' and own custom request serializer it would be possible easily configure logger for google cloud log structure.

Example

Example for google cloud:

private readonly server: FastifyInstance = fastify({
        trustProxy: true,
        ignoreTrailingSlash: true,
        logger: {
            customAttributeKeys: {
                req: 'httpRequest',
                reqId: 'logging.googleapis.com/trace',
            },
            serializers: {
                req: function (req): any {
                    return {
                        requestMethod: req.method,
                        requestUrl: req.url,
                        userAgent: req.headers['user-agent'],
                        remoteIp: req.headers['x-forwarded-for']
                    }
                }
            }
       }
})

Shouldn't it be live inside pino instead of here? If it add too much overhead into pino, then it should be a custom transportor?
