Issue:
Performance monitoring for jobs in queue
Hi there,
first of all, thanks for all you great work!

I correctly receive on sentry all errors and performance tracking info for "normal" web requests in my laravel apps. 

Is there a way to have performance monitoring tracking for jobs that run on queue via database adapter?

Should be nice to have them reported with the job name as transaction key, the same we have for standard request with route name as transaction key. It should respect sample trace ratio configured, of course.. 

If it is already implemented is there some doc to read to configure it? 

Pull request description:
Add tracing support for queue jobs
This adds (opt-in) support for queue job tracing.

When the feature is disabled jobs running on the `sync` queue or with `dispatch_sync` (Laravel 8) will still show up when a transaction is active, but jobs running in a queue worker / Horizon will not generate transactions.

Also adds some other toggles to disable certain span if needed.

Fixes #456.
