cinder.conf should default rootwrap_config path like nova

[Matt Riedemann]

The nova.conf.sample defaults the path for the nova rootwrap.conf file:

https://github.com/openstack/nova/blob/master/etc/nova/nova.conf.sample#L274

The cinder.conf.sample doesn't default the path:

https://github.com/openstack/cinder/blob/master/etc/cinder/cinder.conf.sample#L419

But the cmd.py entry point documents that it should be set:

https://github.com/openstack/cinder/blob/master/cinder/openstack/common/rootwrap/cmd.py#L25

So we should just set it in cinder.conf.sample so it's turned on by default to the proper path like nova does.

Eric Harney and I discussed this with Matt in IRC. Seems that we should change this to be consistent with the other components. I will submit a patch.

    Set rootwrap_config path to rootwrap.conf

    Other components set
    rootwrap_config = /etc/<component>/rootwrap.conf by default.
    This commit brings cinder up-to-date with what other
    components are doing by setting
    rootwrap_config = /etc/cinder/rootwrap.conf by default.

    A couple of test cases needed to be updated to handle the change
    from 'None'.

    Not counting this as a documentation impact as the documentation I
    can find already lists /etc/cinder/rootwrap.conf as the default.
