Allow Omniauth providers to be marked as external

Related to #4009 

With this MR we will be able to allow the user to set which Omniauth Providers they would like to have as external. All users login in via these providers will be marked as external, even if they already had an account before. If the provider is removed form the list of external providers, the users will be marked as internal at their next login.

Move RepositoryArchiveCacheWorker to sidekiq-cron

Closes #15105

See merge request !3663

Add `Gitlab.com?` method

To be used as a feature flag for GitLab.com-only features, such as
welcome emails.

We will be careful to only use this to disable features or functionality
that do not make sense for any installations that aren't GitLab.com. We
will not use this to restrict features from other installations or keep
them "exclusive" to GitLab.com.

Adjust the default trusted_proxies to only include localhost

Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/3538

Omnibus config: https://gitlab.com/gitlab-org/omnibus-gitlab/issues/1208

Tie example config to JIRA screenshot

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/15203

See merge request !3693

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/15203

One use case for this is manually setting the "action" tag for Grape API
calls. Due to Grape running blocks there are no human readable method
names that can be used for the "action" tag, thus we have to set these
manually on a case by case basis.
