Description of problem:
I'm trying to setup a compute resource on GCE, but cannot save it.

Version-Release number of selected component (if applicable):
6.2.1

How reproducible:


Steps to Reproduce:
1. Setup service account etc. on GCE side
2. Fill in the form on Satellite 6.2.1
3.

Actual results:
Form comes back with all fields except for 'client email' still filled. Error in foreman/production.log:

2016-09-08 08:58:18 [app] [I]   Parameters: {"utf8"=>"✓", "authenticity_token"=>"C7HfYbh+CRQzI2NQAGshmU49IayKymMf4Jd94KW7/fY=", "compute_resource"=>{"name"=>"GCE", "provider"=>"GCE", "description"=>"", "project"=>"automationdemo-142810", "email"=>"579721332491-compute.com", "key_path"=>"/etc/foreman/gce.p12", "zone"=>"europe-west1-b", "location_ids"=>[""], "organization_ids"=>[""]}, "commit"=>"Submit"}
2016-09-08 08:58:18 [app] [I] Failed to save: URL can't be blank

Expected results:
Compute resource is saved.

Additional info:
Connection test works fine.

Also, when I add the following code to /usr/share/foreman/app/views/compute_resources/form/_gce.erb, I can save the resource fine:

<%= text_f f, :url, :label => _("URL"), :help_inline => _('Quick fix'), :class => 'col-md-8' %>
