Replace underscore/lodash in subscriptions

Closes #210269

See merge request gitlab-org/gitlab!27444

This metric is used to track the size of updates that need
to be synchronized to Elasticsearch. Since this is a custom queue and
we're not using Sidekiq we needed to implement our own custom monitoring
for it.

This MR just sets a gauge every minute in a cron worker which will
ultimately be available in Prometheus. Later we will build a chart for
this.

user_type column

Don't let the model do all the hard work, split responsibilities.

Use Rails 6 upsert_all to reduce queries and simplify code.

Implemented a generic table that can cater to other
types of daily CI metrics in the future.

Use INSERT DO UPDATE for better handling of conflicts instead
of using with_lock.

Hooks into PipelineSuccessWorker to run a service
that will store the daily code coverage values.

Also adds expect(...).not.toBe to add assurance
that the state actually changed

Closes #202035

See merge request gitlab-org/gitlab!27072

This commit removes redundant logic around a help link from the FE.

Also, avoid private project enumeration by
redirecting 'always'.
