This is an example plugin for adding a background job type.
Enable the plugin by editing the file in config/config.rb:
AppConfig[:plugins] = ['some_plugin', 'jobs_example']
It adds a new kind of job called slow_nothing_job. It doesn't
do anything except sleep for 10 seconds a parameterizable number
of times, and log the fact. It can also be canceled, and can
report its success.
It is intended to demonstrate a minimal implementation for adding a job type from a plugin.
