Context meta & params in metrics events #166

By @dani8art you can set that the broker put some ctx.meta and ctx.params fields to the metrics events.
You can define it in the action definition:

module.exports = {
    name: "test",
    actions: {
        import: {
            cache: true,
            metrics: {
                // Disable to add `ctx.params` to metrics payload. Default: false
                params: false,
                // Enable to add `ctx.meta` to metrics payload. Default: true
                meta: true
            },
            handler(ctx) {
                // ...
            }
        }
    }
}

If the value is true, it adds all fields. If Array, it adds the specified fields. If Function, it calls with params or metaand you need to return with an Object.
