Performance: enable thin provision for lvm

Browse Source 
Currently lvm type as default which is treated as non thin provision.
So it will use dd without sparse to copy data for clone lvm. It will
occupy much disk space and also consumes much cpu/io resource. But
actually in our CI env, thin provision is supported. Let's enable
this feature to get better performance.
