Write archival/caching worker

[pudo]

Write a worker that scans all packages in a ckan instance and uploads the data to storage.ckan.net or another suitable storage system.

• Naming scheme?
  • Bucket: {ckan-instance-id}-{package-name}? {ckan-instance-id}-{package-id}?
    • What happens if names change
  • File: filename? hash?
• Store hash back on ckan instance?

The caching worker will consumer update notifications and fetch packages.

Extra points for:

• Properly checking for source file modification (Last-modified, Etag)
• Using PIP VCS Backends for retrieval
• OFS/S3 Storage
