Collect and report download statistics / analytics

[anarchivist]

Given the following assumptions:

• POD is intended to be an environment to support consortial resource sharing
• POD data is subject a data sharing and user agreement, and is not openly available

We need a way to collect basic download statistics and analytics:

• Total number of downloads of aggregate data: original uploads, normalized uploads as MARCXML, normalized uploads as MARC21
• Total number of downloads of individual institution data: original uploads, normalized uploads as MARCXML, normalized uploads as MARC21, deleted records
• Per institution downloads of aggregate data: original uploads, normalized uploads as MARCXML, normalized uploads as MARC21
  • Option to break out by token?
• Per institution downloads of individual institution data: original uploads, normalized uploads as MARCXML, normalized uploads as MARC21, deleted records
  • Option to break out by token?

Breaking out downloads by token is probably only useful if we include some additional descriptive info for tokens (#197).

We're currently collecting this information using ahoy:

#<Ahoy::Event id: 11, visit_id: 8363, user_id: 11, name: "Download", properties: {"attachment_id"=>3175, "attachment_name"=>"files", "byte_size"=>3073505837, "content_type"=>"application/zip", "filename"=>"penn_02DEC2020.zip", "organization_id"=>"penn"}, time: "2020-12-02 14:46:11">

The Ahoy::Event has information about what file was downloaded, the org the file belonged to, and some stats about the file. The associated visit has the user, token, and relevant organization of who downloaded the data.
