Issue #180 #191 Allow multiple network configuration files and support for RHEL

[gbraad]

Fixes #180, #191

Needed for allow multiple network configuration files: https://github.com/minishift/minishift/issues/1457

Signed-off-by: Gerard Braad me@gbraad.nl

Testing on VirtualBox with the following configuration files:

cat /var/lib/minishift/networking-eth0

DEVICE=eth0
USEDHCP=y

cat /var/lib/minishift/networking-eth1

DEVICE=eth1
IPADDR=192.168.235.100
NETMASK=24
GATEWAY=192.168.235.1
DNS1=8.8.8.8
DNS2=8.8.4.4

Should also allow to use DHCP on multiple interfaces cat /var/lib/minishift/networking-eth1

DEVICE=eth1
USEDHCP=y

[gbraad]

Forcing assignment of the address by DHCP on both network interfaces; eth0 and eth1, as it is easier for us to et device information from the lease file.

[gbraad]

Have to store the initial config as part of the userdata as /var/lib/minishift gets removed on initial startup

[gbraad]

dhclient messes up the DNS configuration when used as two different interfaces. Need to check how NM handles this (up script?). At the moment it only registers DNS for the last device 192.168.42.1, while 192,168.122.1 actually provides NAT.

[gbraad]

Modifications to /usr/sbin/dhclient-script were needed to keep the old nameservers.

Added support for

DISABLED=y

@praveenkumar This needs testing for RHEL, as it also includes the #191 patches.

[gbraad]

@anjannath added a $DEVICE existence check, but the issue actually comes from Minishift

@praveenkumar updated with ${hvkvp_repo_url}
