impl: improved poll job lifecycle report

Poll jobs now have a random friendly name that changes each time
a new job is created, and the logging for when the jobs are created
or cancelled is also improved. The idea behind this commit is to improve
debugging sessions on client logs by:
- having clear log lines saying when a job is created/destructed
- easy to remember and cross-match job names (instead of cryptic java reference values)
