Dnsmasq bind on localhost address after reboot of Fuel Master

[slava valyavskiy]

Detailed bug description:
 Dnsmasq hangs on localhost address after reboot of Fuel Master instead of ip address of corresponding pxe interface and it makes network checker fails on 'check_repo_availability' task.
Steps to reproduce:
 1. Install Fuel Master node
 2. Reboot Fuel Master node
Expected results:
 FM is able to resolve mirantis.com.
Actual result:
 FM is not able to resolve mirantis.com.
Reproducibility:
 Always
Workaround:
 Restart Dnsmasq service
Impact:
 Any network resource can not be resolved by name from FM
Description of the environment:
 Versions of components: Fuel 10.0
Additional information:
######
[root@nailgun ~]# netstat -tupln4 | grep dnsmasq
tcp 0 0 127.0.0.1:53 0.0.0.0:* LISTEN 1214/dnsmasq
udp 0 0 127.0.0.1:53 0.0.0.0:* 1214/dnsmasq
udp 0 0 0.0.0.0:67 0.0.0.0:* 1214/dnsmasq
#####

 We are binding dnsmasq to particular interface by its biosdevname and it seems that dnsmasq tries to occupy this interface before system has a chance to rename it from its 'eth*'naming scheme.

My fuel master node is a VM inside another VM. It seems that slow performance may be a reason of fail. Anyway, it works fine in 9.0 release.
