KeyError: key not found: :retain_row_count

[bjeanes]

The Que::Scheduler::Jobs::QueSchedulerAuditClearDownJob tries to pull the row count from passed options with :retain_row_count, a Symbol:

que-scheduler/lib/que/scheduler/jobs/que_scheduler_audit_clear_down_job.rb

Line 31 in 2f7f93c

retain_row_count = options.fetch(:retain_row_count)

I'm not sure if this is due to something ActiveJob is messing with (even though it seems this job is not wrapped by ActiveJob's JobWrapper).

The example from the project README defines the schedule in the YAML file with a string key:

que-scheduler/README.md

Lines 194 to 197 in 2f7f93c

	Que::Scheduler::Jobs::QueSchedulerAuditClearDownJob:
	cron: "0 0 * * *"
	args:
	retain_row_count: 129600

At least in my project and configuration, defining this with a Symbol key specifically is forbidden by Psych:

Que::Scheduler::Jobs::QueSchedulerAuditClearDownJob:
  cron: "0 0 * * *"
  args:
    :retain_row_count: 129600

causes a Psych::DisallowedClass: Tried to load unspecified class: Symbol.

Perhaps I am missing something obvious here, but I think this clear job may have been written assuming a hash with indifferent access or Hashie or something, but this assumption doesn't seem to hold true (at least in all circumstances).

Perhaps the job could be adjusted to check for both a Symbol and a String key, esp given #214 and #207
