Description
Right now if you want to run integration tests you have to create a binary of op-rbuilder. The framework will spawn the binary process on the background alongside other processes (i.e L2P-497). This is a bit cumbersome because if you might forget about building the binary again after your changes, and it takes some time to figure out why the behaviour of the test is the same.
Instead, we could do like we do in Rollup-boost https://github.com/flashbots/rollup-boost/blob/main/tests/common/services/rollup_boost.rs#L58 which is running the op-rbuilder as an internal process.
