Test changes in descriptors
Working on #30733 (moved) asn pointed out that there're no tests to check the changes in descriptors.
It'll be easier to create these tests when:
- sbws can use chutney (#33150 (moved)) so that the test network lives longer than the 1st consensus
RelayListcan be initialized with different consensus/descriptors and not only a controller (#29717 (moved))
- have an external tool that check the generated bandwidth files in the Tor network and detects changes in the descriptors (#33152 (moved))
Maybe we should include this ticket as part of #33121 (moved)
