    During opencontrail attach vifs the containers use dhclient to lease an ip address.
    When bulk container create request is sent, the /var/lib/dhcp/dhclient.leases file is overwritten.
    Due to the corrupted file Successive docker containers are not getting IP lease
    as the dhclient command is failling .

Fixing it by creating separate lease files for each docker container.
