add a helper 'find_lxc_ip_address' to fetch IP address of container from
its network namespace using lxc-info.
for the moment it can be queried with the pct tool:
$ pct status 1000 --verbose
cpu: 0
cpus: 1
disk: 6422528
diskread: 368640
diskwrite: 0
ipaddress: 192.168.31.83 <----
maxdisk: 4294967296
maxmem: 536870912
maxswap: 536870912
mem: 864256
name: CT1000
netin: 3281265
netout: 15794
pid: 34897
status: running
swap: 94208
type: lxc
uptime: 11088
vmid: 1000
