Create veth peer in namespace.

 * Update veth pair creation to set the namespace of the peer
   device on creation rather than subsequently adding it to the
   namespace.
 * This change supports kernels with limited namespace support
   (e.g. RHEL 6.5) so long as ovs_use_veth is set to True.
 * Addresses bug 1171727

in dhcp_agent, always use quantum.conf root_helper

Fixes bug #1178003.

For the most part, the dhcp agent uses the root_helper setting from the [AGENT]
section of /etc/quantum/quantum.conf. However, in a couple of spots, the
root_helper setting from the [DEFAULT] section of /etc/quantum/dhcp_agent.ini
was being used.
