Draft: Use project level settings for Beyond Identity push check

What does this MR do and why?

• Integrations can typically be configured by admins at the instance level as well as from the project and group levels by project/group admins.
• For Beyond Identity we want to restrict configuring the integration to instance admins only but want to be able disable it at the group or project level as well.
• This change is to add graphql resources to facilitate a UI (#454372 (comment 1878126479)) that will enable admins to add/delete project level settings for Beyond Identity.
  • Adding arguments for group level settings will be in a future MR
