bin/openquake:

Show only calc info (not "job") in bin/openquake console output.
logs:

Include calc domain (hazard|risk) and calc id, instead of job id
in log messages.
engine:

Update call to logs.init_logs_amqp_send; there's a new func signature.

Update call to logs.init_logs_amqp_send.

Update log message format to include calc domain (hazard|risk)
and calc id.

Updated a comment.
supervising/supervisor:

Corrected LOG_FORMAT format string.
supervising/supervisor:

Updated log handler constructors to accept a `calc_domain` (hazard|risk)
and a `calc_id`, instead of a `job_id`.
supervising/supervisor:

Updated supervisor logging so that the job_id is no longer reported;
instead we report "hazard|risk <calc_id>".

Since the user interacts with 'calculations' in several of the command
line options, it makes sense to log about the calculation, not the job.
tests/supervisor_test:

Fixed some broken tests, per logging/supervisor changes.
