TCA reports an error in case of slow connection

closes #18299 (closed)

This MR depends on !422 (merged)

This implements these changes to the timeout thing:

• if we don't reach bootstrap_phase = 10 (meaning we can establish no connection to any Tor relay) in 30 seconds, we consider this an error
• after reaching bootstrap_phase=10, we wait for 120seconds for bootstrap to be completed. Otherwise, we consider this an error.

Tips for testing:

• https://paste.debian.net/1196989/ ready-made script to make both upstream and downstream slow
