Delete auto_deploy_on_security flag, making it the default
As a counterpoint to #1026 (closed), once we're satisfied with the functionality behind this feature flag we should delete it and make it the default.
As suggested by gitlab-org/release-tools!1176 (comment 410175097), we may want to remove the auto_deploy_path
method from BaseProject
, as once this feature flag is removed it will simply delegate to security_path
unconditionally.
