Block Production\Publishing Performance threshold based on flow

[tbenr]

We currently have only one threshold but the definition of "slow" is function of the flow that we are running.

Builder flow have external interaction that adds latency, both on production (builderGetHeader step) and on publishing (builderGetPayload step).

So we currently have 300ms and 1000ms as threshold for production and publishing respectively, just to be able to catch slow flow even running local only flows.
Once having them separated, we could have a 750ms and 1500ms for builder and maybe have an even shorter deadlines for local flows.
