the voting LVM job (manila-tempest-minimal-dsvm-lvm-centos-7)
has been failing for a while due to the issue identified
in . The fix for the issues didn't suffice for CentOS,
and we use CentOS because of missing IPv6 related fixes
in Xenial's nfs-utils package. to avoid impacting helpful
backports to these branches, this commit introduces a
new voting job called "manila-tempest-dsvm-lvm-em-only"
that deploys manila with the LVM driver on Xenial and
runs IPv4 scenario tests.
