Midonet creates DHCP data even when DHCP is disabled

[Joe Mills]

When the user creates a subnet, there is an option to disable DHCP. However, the Midonet plugin currently ignores this option and creates DHCP information for each subnet created.

    Do not add DHCP info to subnet if DHCP is disabled

    Currently the midonet plugin will add default DHCP information to
    each subnet even if the subnet is configured to have DHCP disabled.
    This change addresses this by checking the DHCP settings while
    creating a subnet, and only adding DHCP information if DHCP is
    enabled.
