Recruit potential default bridges from set of long-running bridges

We would like to set up more default bridges. One way to recruit more is to look for non-default bridges that have 1) high capacity, 2) have been around for a long time, and 3) have a stable uptime. Ideally, we should also know the person who runs the bridge, as stated in our list of criteria for setting up a new default bridges.

Let's have a look at archived bridge data and extract a list of default bridge candidates.
