provider on CentOS 6

[lukebigum]

Following on from the second issue reported in #129, I'm modifying the redhat network_config provider to work on CentOS 6. I've ran into an issue where parameters that are undef in a Puppet manifest are being written to disk as "KEY=absent". The issue is reproduced in an acceptance test I've added to https://github.com/lukebigum/puppet-network:

git clone git@github.com:lukebigum/puppet-network.git
cd puppet-network
ln -s centos-65-x64.yml spec/acceptance/nodesets/default.yml
bundle exec rake acceptance

And an example of the failed test:

3. network building various network configurations File "/etc/sysconfig/network-scripts/ifcfg-eth0" content should not match /^IPADDR=/
   Failure/Error: its(:content) { should_not match /^IPADDR=/ }
   expected "ONBOOT=yes\nslave=yes\nIPADDR=absent\nDEVICE=eth0\nNETMASK=absent\nHOTPLUG=yes\nmaster=bond0\nMTU=absent\ntype=Ethernet\nBOOTPROTO=static\n" not to match /^IPADDR=/

I can fudge it by explicitly filtering out "value != :absent", however there is another issue where the puppet type is not idempotent (continually applies) so I think there is something lower down interfering with the provider reading and writing Type parameters properly.

Is anyone able to assist?

#136 now has the code to fix this.
