- this change extends the tools/cleanup-containers script to
support a grep extended regex as a first paramater.
- if tools/cleanup-containers is called with a grep extended
regex string as a first paramater, only containers mataching
that regex will be cleaned up.
- e.g. tools/cleanup-containers "neutron|openvswitch"
will cleanup all container whoes name contains either neutron
or openvswitch.
