In the DIB build the DHCP code (provided by the dhcp-all-interfaces element) races with the service starting IPA. It does not matter for deployment itself, as we're waiting for the route to the Ironic API to appear. However, for inspection it may result in reporting back all NIC's without IP addresses. Inspection fails in this case. This change makes inspection wait for *all* NIC's to get their IP addresses up to a small timeout. The timeout is 60 seconds by default and can be changed via the new ipa-inspection-dhcp-wait-timeout kernel option (0 to not wait). After the wait inspection proceedes in any case, so the worst downside is making inspection 60 seconds longer. To avoid waiting for NIC's that are not even connected, this change extends the NetworkInterface class with 'has_carrier' field. Closes-Bug: #1564954 Change-Id: I5bf14de4c1c622f4bf6e3eadbe20c44759da5d66
