When doing a leapp upgrade using Satellite job, if we are using EUS repository, job failed because channel_opts variable is not set.

after digging in the job templates, it's missing a "=" when setting channel_opts ansible variable using ruby code on https://github.com/theforeman/foreman_leapp/blob/master/app/views/foreman_leapp/job_templates/leapp_upgrade.erb#L26
