Update docker for CentOS issues in AWS and general variables. 1. AWS has issues with ext4 (use xfs instead for CentOS only) 2. Make sure all the centos config files are include in the systemd config 3. Make sure that network options are set in the correct file by os family This allows downstream items like opencontrail and others change variables in expected locations.
