Description of problem:

A host group is leveraging erb syntax for several of its parameters. An example of the erb synxtax used for one of the parameters:

Name            Value
dns_primary     <%= @host.subnet.dns_primary %>

This is working when the host group is attached to a host.

However, when trying to use the host group in the global registration template, an error is thrown:

 Danger alert: There was an error while loading the data, see the logs for more information.

The production.log shows this error:

How reproducible:
always

Is this issue a regression from an earlier version:

no

Steps to Reproduce:

1. Create a host group, and add a parameter which is using erb syntax for its value.

2. The value for one of the parameters <%= @host.subnet.dns_primary %>

3. Try to use this host group in the global registration page.

Actual behavior:
Unable to use a host group which is leveraging erb syntax in one of its parameters in the Satellite's global registration page.

Expected behavior:
Expect for the global registration to allow a host group to use erb syntax.

Business Impact / Additional info:

This is preventing hosts from being registered with these parameters.
