lxc-veth-check wires veth pairs incorrectly

[Paulo Matias]

After accidentally wiping up all veth pairs wired to br-mgmt (by doing an ifdown br-mgmt), I ran /usr/local/bin/lxc-veth-check in order to create them again.

Per my config, the eth1 interface from all containers should be wired to br-mgmt. However, as the script greps for the corresponding config file, it happens to find the one for eth10 instead of eth1:

---
controller-03_neutron_agents_container-6c550730 had a broken veth 6c550730_eth1 not being plugged into br-vxlan: this issue is now resolved
---

It might also find configs for eth11 or eth12 because both contain the string "eth1".

Therefore, the grep below should be modified to check for a word boundary.

grep -l "${net_info}" /var/lib/lxc/${container}/{config,*.ini}

I will submit a patch to gerrit right now.
