In a longevity test reported in scylladb/scylladb#16668 we observed that NORMAL state is not being properly handled for a node that replaced another node. Either handle_state_normal is not being called, or it is but getting stuck in the middle. Which is the case couldn't be determined from the logs, and attempts at creating a local reproducer failed. Thus the plan is to continue debugging using the longevity test, but we need more logs. To check whether `handle_state_normal` was called and which branches were taken, include some INFO level logs there. Also, detect deadlocks inside `gossiper::lock_endpoint` by reporting an error message if `lock_endpoint` waits for the lock for too long.
