Enabling / disabling "Enforce SSO" must be done through 3scale Admin Portal UI on the SSO Integrations screen in Account Settings.
This request is to add an API to enable/disable "Enforce SSO" that can be used by automation to simplify operations / deployment processes.
QE notes: need to test also scenario when there is no SSO seted up, you should be able to enforce sso otherwise you can lock users out of 3scale
