User can configure a list of Roles which will be updated when a Site is created in the Site Factory. Those Roles should have "user/login" policy with at least one limitation. If not then the error is written in logs. If Role has no "user/login" policy then nothing happened (policy is not added)

Identifier of Roles could be defned in `config/packages/ezplatform_site_factory.yaml` file.

ez_platform_site_factory:
 enabled: true
 update_roles: [20]
