Webservice copy of template-based LTI (NOT instance-wide)

Use case: Templates are used as basis to create sites via webservice.
LTI is configured directly in the template, rather than instance-wide because some departments have purchased/subscribed to LTI- tools for their department rather than an institution-wide license.
Any given department may have its sites created via a template.

This Jira should resolve:

• Need for someone to click into LTI copy in order to 'fix it'
• Security issue in that an instructor in one of the resulting sites could now see the key, secret and URL and potentially harvest that information for use elsewhere.
