Add analytics configurations

[elrayle]

Descriptive summary

This describes how to setup the new Hyrax analytics configuration. Analytics are temporarily turned off in this PR to avoid exceptions being thrown.

How analytics are turned off

Analytics is temporarily turned off by setting config.analytics = false in /config/initializers/hyrax.rb.

Before turning on

The following ENV variables need to be setup for use in /config/analytics.yml:

analytics:
  google:
    analytics_id: <%= ENV['GOOGLE_ANALYTICS_ID'] %>
    app_name: <%= ENV['GOOGLE_OAUTH_APP_NAME'] %>
    app_version: <%= ENV['GOOGLE_OAUTH_APP_VERSION'] %>
    privkey_path: <%= ENV['GOOGLE_OAUTH_PRIVATE_KEY_PATH'] %>
    privkey_secret: <%= ENV['GOOGLE_OAUTH_PRIVATE_KEY_SECRET'] %>
    client_email: <%= ENV['GOOGLE_OAUTH_CLIENT_EMAIL'] %>

To turn on

Remove config.analytics and config.google_analytics_id from /config/initializers/hyrax.rb to avoid conflict with new configuration.

Set ENV['HYRAX_ANALYTICS'] = true to turn analytics back on.
