Remove three consecutive attempts to build a circuit
Currently, a relay is measured to when measuring a relay, circuits are attempted to be built a maximum of 3 consecutives times when the previous measurements fail attempt fails, but in most of the cases, when measuring a relay building a circuit fails the first time, it will also fail the consecutives times.
The relay will be measured anyway in the next iteration.
Based on what we talked in https://trac.torproject.org/projects/tor/wiki/org/meetings/2019BrusselsNetworkTeam/Notes/SBWSRoadmap#Questions
Edit: the three attempts happen when trying to build the circuit when measuring a relay, but it's not three attempts to measure the relay.
