Initial work for Lxc_interface type
Initial rspec tests for Lxc_interface type
Fixed test for parameters and add index.

Type should be ready, expect only minor changes.
Flags to 'up' and make container to be required.
Network type default to veth
Container name is now required
Initial work for lxc_interface provider
#create and its tests for lxc_interface
lxc_interface should be ready for a real test
@resource is not yet there, have to use self
seems order matters here
Added note to fix ipv4 as bindings do not return
mask.
Added note to fix/remove flags, down does not work
Removed tags, have not found any useful use for it
ipv4 getter should be working now, skipping test
until I find a good way for it.
missing #save_config in setters
Seems the item has to cleared to avoid dups
Hopefull the getter for ipv4 is working, it's a
workaround until liblxc > 1.0.5 is released
Worse or better?
Typo, seems to work
