New LVM cookbook

Hi,

I removed dependency on gems 'di-ruby-lvm' and 'di-ruby-lvm-attr'. As we discussed upstream cookbook require Chef 11 and additional packages. I would like to propose and fork lvm cookbook since we will not migrate to Chef 11.

I will try to post this cookbook to upstream but I doubt in success, because they propose us to upgrade to Chef 11 and magician circle will close.

Cookbook works fine and for integration with drbd will be perfect.
