API for accessing and configuring LTI registrations in a root account.
LTI Registrations can be any of:
1.3 Dynamic Registration
1.3 manual installation (via JSON, URL, or UI)
1.1 manual installation (via XML, URL, or UI)
The Dynamic Registration process uses a different API endpoint to finalize
the process and create the registration. The has more details on that process.

Enable or disable the specified LTI registration for the specified account. To enable an inherited registration (eg from Site Admin), pass the registration’s global ID.
Only allowed for root accounts.
Specifics for Site Admin: “on” enables and locks the registration on for all root accounts. “off” disables and hides the registration for all root accounts. “allow” makes the registration visible to all root accounts, but accounts must bind it to use it.
Specifics for centrally-managed/federated consortia: Child root accounts may only bind registrations created in the same account. For parent root account, binding also applies to all child root accounts.
