Cleanup old metrics dashboard code

  • Remove metrics dashboard related code from EnvironmentsHelper and EE::EnvironmentsHelper.
  • Remove old Prometheus API route and controller: app/controllers/projects/environments/prometheus_api_controller.rb.
  • Stop creating an environment in lib/gitlab/database_importers/self_monitoring/project/create_service.rb?
  • Remove old view and js files.

Keep in mind that dashboard embeds have to continue working with the old and new URLs.
