[Fullstack] Wait 10 seconds to ensure that MAC address is configured
In Linuxbridge and OVS PortFixture, when port is created, in the fake
vm's namespace it needs to have correct mac address configured.
It seems that for some reason it's not properly configured sometimes and
that may cause failure of e.g. DHCP tests.
So this patch adds retries for 10 seconds to ensure that MAC address is
configured to the one which should be.
Closes-bug: #2000150
