dont include lxc cookbook and aufs recipe on ubuntu 13.10 and up

[bkw]

this essentially adds upport for ubuntu saucy (13.10) and hopefully following versions.
See discussion in #32.

AFAICT, the LXC cookbook shouldn't even be required for 12.04+ as well. Is there any reason we can't make this an attribute so I can completely disable LXC/AUFS on any supported Ubuntu?

[bkw]

We still need the aufs recipe for 12.04 with the old kernel though.

Fix coming.

I'll test your branch in my local docker dev VM. Thanks!

[jayofdoom]

LGTM. Docker still installs and runs properly in my Ubuntu Precise VM.

This change will break fresh installs with install_type = binary, which is why LXC dependency was originally included in the cookbook (before the docker packages came around).

We can handle this various ways:

• leave include_recipe 'docker::lxc' in docker::default and only install lxc packages in docker::lxc
• re-add with conditional include_recipe 'docker::lxc' if node['docker']['install_type'] == 'binary'
• maybe something more elegant?

[jayofdoom]

I'd be +1 to option 2 -- where we only require docker:lxc if you're using 'binary' install type.

[jayofdoom]

Based off this branch, I implemented option 2 here: #37

Thanks!
