MdeModulePkg: Update Ip4Dxe driver to support Ip4Config2 protocol,

a new behavior seemed to come in to the network stack that was not present before: It appears now that as soon as the DHCP Service Binding protocol is installed the DHCP process will be initiated (see Ip4Config2OnDhcp4SbInstalled).  This differs from past behavior where DHCP would only occur if a driver or application specifically did Configure() on the network interface.

For some systems this is problematic because they need to defer DHCP until it is certain that the network interface will be used for something.

Can you provide the reason for this change?  Can we have a policy (PCD) to disable this mode of operation?

Thanks,

Eugene
