The odl-sfc-ios-xe-renderer feature is generating OutOfMemory errors in the distribution SingleFeature Test, which is causing the distro test to take more than an hour.

The feature has been commented out of the distribution in this patch:

When the Memory consumption issue is fixed in the feature, please submit a patch to the integration/distribution repo to activate the feature again.
