Is sbws weighting some relays too high?

Before we deploy sbws to the rest of the bandwidth authorities, we should check if it is weighting some relays (or some ASes) much higher than torflow.

We should also check for bugs in sbws, that weight existing large ASes too high: https://metrics.torproject.org/rs.html#aggregate/as

i think the main reason why this is happening is because:

• #33831 (moved): relays without observed or average bandwidth in the descriptors are not scaled, but still added to the bwlines without vote=0
• relays without that bandwidth in the descriptor but bandwidth burst (dunno why they have bandwidth burst and not the other, but i've seen it happening), would scale against bandwidth burst, which is higher

Since #33590 (moved) is a duplicate of this, adding here the info starlight added and closing it:

Let's also check this as part of #33947 (moved)

Parent: #33121 (moved) to #33947 (moved)

Last Saturday, 23th May, maatuska has updated to sbws version 1.1.0+84.g3033421 (current maint-1.1 branch) and can be observed that the total consensus bandwidth is decreasing close to the rest of bwauths. i'm not closing this ticket yet cause i'd like to give an explanation on why i think this happening and because there are still some relays being measured too high (see https://trac.torproject.org/projects/tor/ticket/33947#comment:2)

changed time estimate to 16h
