Make numismatics indexing into Sidekiq background job

[maxkadel]

What maintenance needs to be done?

Turn the process that indexes coins into a background job using Sidekiq

Level of urgency

• High
• Moderate
• Low

Why is this maintenance needed?

Right now this runs in the terminal on the server, which runs that risk that if the server is restarted, or the terminal session is interrupted, the job will not run and will have to be manually re-started.

Acceptance criteria

• If this change touches any of the files referenced in .rubocop_todo.yml create a new ticket to address the rubocop todo.
• The task rake numismatics:index:full sets of a background job or jobs
• The background job is idempotent, meaning if it gets re-started it will not create issues
• The background job incorporates a check that the sneakers workers are off in production
• The job logs to the expected sidekiq log location

Implementation notes, if any
