Figure out whether there are enough "FlowCtrl=1-2" Exits that are sufficient for Exit selection

We need to know if there's enough for that Exit bw threshold we discussed, where an exit has to be 2X faster than the measured node, and not get overloaded by measurement.

It might be enough to check "have the fastest Exits in the network upgraded to 0.4.7"

changed milestone to %Network Health OKRs 2022 Q1-Q2 (Metrics excluded)

added Doing label

assigned to @juga

added K4 O3 S61-O2-Maybe - FINISHED Sponsor 61 - FINISHED labels

changed time estimate to 2h

@juga: I started with 2h estimation, please adjust if you think that's nonsense.

so far looks like it was a good estimation ;)
