tc writing: allow different log level

... for failures instead of the binary strict_logging. In this
way, we can log at log level Error in the serve instance, and for
the client at level Warning or Info, depending on whether failure
is expected (i.e., if targets are potentially taken from a serve
endpoint) or not.
