Set watcher pause on all nodes

Instead of just setting the watcher pause file, which isn't replicated,
RPC is used to set it on all nodes (where possible). This means that
after an outage of the master node and a following master-failover, the
watcher will still be paused....

Improve logging of new job submissions

This addresses issue 290: when receiving new jobs, logging is
incomplete, and we don't have the job ID and/or summaries
logged. Only later, when the job is queried for or being processed, we
know more.

This is not good when troubleshooting, so let's improve the initial...
