Add missing argument max_size in libvirt driver

max_size argument was added in commit 3cdfe894ab58f7b91bf7fb690fc5bc724e44066f,
but missing  in _create_ephemeral and _create_swap method, which cause
exception raised when caching ephemeral and swap disk files of the instance.

Add test for _create_ephemeral used with max_size parameter
and test _create_swap method
