4986ce7cfb devicemapper: Create a method to get device info with deferred remove field
Deferred reove functionality was added to library later. So in old version
of library it did not report deferred_remove field. 

Create a new function which also gets deferred_remove field and it will be
called only on newer version of library.

6964ab94be devicemapper: Add helper functions to allow deferred device removal
A lot of time device mapper devices leak across mount namespace which docker
does not know about and when docker tries to deactivate/delete device,
operation fails as device is open in some mount namespace.

Create a mechanism where one can defer the device deactivation/deletion
so that docker operation does not fail and device automatically goes
away when last reference to it is dropped.
