[ENG-9705] osfmetrics using es8

[aaxelb]

Ticket

• ENG-9705

Purpose

make osfmetrics use data stored in elastic8 (following #11700 )

Changes

• change all api using es6-based osf.metrics to use es8-based counterparts
• change periodic reporters (in osf.metrics.reporters) that use CountedAuthUsage (es6) to use OsfCountedUsageEvent (es8)

Side Effects

• simplify api view mixin for preprint views and downloads (less generic; more hard-coded)
• changes according to different djelme base classes -- e.g. CyclicRecord.cycle_coverage (generic semver-like time string) instead of DailyReport.report_date/MonthlyReport.report_yearmonth
• usage counts now have more consistent deduplication
• (because it seemed easy and good) add experimental /_/metrics/reports/<reportname>/ that reuses api.base.elasticsearch_dsl_views.ElasticsearchListView to give a more usable/consistent jsonapi view than (the honestly kinda janky) /_metrics/reports/<reportname>/recent/
• some things were easier to delete than maintain -- next PR would have deleted them anyway, and will delete more
  • various es6-entangled tests
  • saving usage events to es6
  • preprint views/downloads on all but preprint-detail view
  • management commands:
    • make_dummy_pageviews_for_metrics
    • metrics_backfill_pageviews
    • metrics_backfill_summaries
    • metrics_backfill_user_domains

QE Notes

api changes:

• structure and counts unchanged (but data is coming from a different place):
  • /v2/institutions/<id>/metrics/summary/
  • /v2/institutions/<id>/metrics/users/
  • /v2/institutions/<id>/metrics/departments/
• unchanged in structure, but counts might change due to more effective deduplication:
  • /v2/preprints/<id>/?metrics[views]=<timespan>
  • /v2/preprints/<id>/?metrics[downloads]=<timespan>
  • /_/metrics/query/node_analytics/<id>/<timespan>/
  • /_/metrics/query/user_visits/
  • /_/metrics/query/unique_user_visits/
• slightly changed in structure (but shouldn't break anything):
  • /_/metrics/reports/<reportname>/recent/ -- some additional fields and different "type"
• removed:
  • /_/metrics/preprints/views/
  • /_/metrics/preprints/downloads/
  • metrics params on preprints list view /v2/preprints/
  • metrics params on preprint providers /v2/providers/preprints/ and /v2/providers/preprints/<id>/

user-facing features that should still work as before:

• institution admin dashboard (summary + users tab)
• preprint view/download counts (may decrease due to better deduplication)
• project/registration analytics page (some usage counts may decrease due to better deduplication)
