Uses ActiveRecord::Associations::Preloader to preload data
from MembersPresentation to avoid N+1 queries.

Adds User#group_sso? method due to ActiveRecord cop,
and checks loaded? in case this method ends up being reused
without preloaded data.

Resolve "Operations Homepage MVC"

Closes #5781

See merge request gitlab-org/gitlab-ee!7341

attr_encrypted expects models to have their attribute methods defined,
or it will override them with standard Ruby accessors. Migration specs
that rolled back the state of the database after columns were migrated
to encrypted values were interfering with these definitions. To ensure
that the SystemHook specs pass, we need to call
`SystemHook.define_attribute_methods` to ensure that attr_encrypted sees
the right methods that reflect the latest state of the database.
