docker: don't use custom run-os-net-config

The script run-os-net-config[1] copies in ifcfg-* from the host before
running os-net-config. Apparently it was done this way because the
other scripts in /etc/sysconfig/network-scripts/ differed between host
and agent container. This should be less of an issue now that host and
heat-agents run centos-7 (even when the host is atomic)

tripleo-heat-templates recently changed to running os-net-config in a
deployment script instead of an os-refresh-config script [2]. This
means that our current run-os-net-config approach is currently
resulting in os-net-config being executed twice.

Another issue with run-os-net-config is that it copies ifcfg-* from
host to container, but not back again. This means that rebooting the
server will result in unconfigured interfaces until os-net-config is
somehow run again.

This change bind mounts /etc/sysconfig/network-scripts/ from the host
and uses the conventional approach to running os-refresh-config.

This may fix the issue where compute nodes are losing network
connectivity, so
Closes-Bug: #1646897
