Public bug reported:
Suppose we already have the following resources：
network_A,
datapath_A corresponds to network_A.
subnet_A,
And use subnet_A create a vm_A. The vm_A's port is bound to datapath_A in the
port_binding table.
If we set enable_dhcp to False for subnet_A, the metadata agent will delete the
corresponding namespace for network_A to stop the metadata service. If, at this
point, we reconfigure subnet_A's DHCP, the metadata agent will not recreate the
namespace corresponding to network_A to provide metadata services.
