emc scaleio uses drv_cfg exe which isn't in volume.filters

[Matt Riedemann]

This came up here:

https://review.openstack.org/#/c/194454/13/etc/nova/rootwrap.d/compute.filters

The emc scaleio volume driver is running a command as root which isn't in cinder's default volume.filters:

https://github.com/openstack/cinder/blob/master/cinder/volume/drivers/emc/scaleio.py#L989

I have no idea how the emc scaleio third party CI is passing, they probably just hack it in as part of their setup, but this was the link to a passing job - but there are no logs:

Here is a CI example of it working:

This one will be fixed once the following bugs are fixed:

os-brick needs to provide it's own rootwrap filters file:

ScaleIO driver should use os-brick connector:

    Add ScaleIO Cinder driver commands

    ScaleIO Cinder driver commands are currently missing from
    Cinder's rootwrap filters. Since we are not using os-brick's
    rootwrap filters in Liberty, these missing commands need to be
    added to Cinder's rootwrap filters.
