Pinning #286, should be interesting to this feature.

This seems to be the not first time this is raised as an issue, see #369. We could probably leverage the logger like in #370.

`kernel.build_dir` [has been added in 5.2](https://github.com/symfony/symfony/commit/e98fdc7073a3f0c4db08efe5571d7dce5f74d15d), we need to make that optional, depending on the SF version.

This should be a nice feature. In any case, it's already possible with the `transport_factory` option: you need to write a class that implements the `TransportFactoryInterface` and just returns the...

As of now, the Symfony client is used as default transport not just by this bundle, but by the whole PHP SDK. Hence, [that piece of code](https://github.com/getsentry/sentry-php/blob/ecbd09ea5d053a202cf773cb24ab28af820831bd/src/HttpClient/HttpClientFactory.php#L116) doesn't know if...
