Related to internetee/accreditation_center#131

In these files add env conditions:

repp/v1/registrar/accreditation_results_controller.rb
repp/v1/registrar/accreditation_info_controller.rb
api/v1/accreditation_center/base_controller.rb

Rails.env.development? || Rails.env.staging? || Rails.env.test?
When will added new env demo, then this env conditions need to change to Rails.env.demo?

Added a new condition for displaying an endpoint in an isolated environment. To do this, you need to add the key in application.yml allow_accr_endspoints: 'true' for the test registry environment. Then endpoints for working with registry production will be available. For other environments, for example, for staging and production, this key can be omitted.

in application.yml need to add these keys:

registry_demo_registrar_port: '3000'
registry_demo_registrar_results_url: 'http://registry.test/api/v1/accreditation_center/results'
registry_demo_registrar_api_user_url: 'http://registry.test/api/v1/accreditation_center/show_api_user'
registry_demo_accredited_users_url: 'http://registry.test/api/v1/accreditation_center/list_accreditated_api_users'

These links below are endpoints
instead http://registry.test/ should base url of demo env registry

Job, which check all user api in demo env database called by SyncAccreditedUsersJob.perform_now
