Attach a new trusted OpenID Connect Identity Provider to an App.
The App must be constrained to a Project. To constrain an App to a Project, use the Access Manager -> Apps -> My Apps -> Edit app -> specify "DEFAULT ACCESS TO A PROJECT", and check "Allow access only in this project".
An App may have at most 2 IdentityProviders attached to it.
Access Control:
- The calling principal must have either "manage" action permission for the resource "{app}" in the "account" service or "readIdentityProviders" action permission for the callers "{realm}" in the "account" service.
- The calling principal MUST NOT include a project scope.
