The idea is to do iterative migration of an image file, in the following way:

1. Turn write tracker feature on. Now the kernel will keep track of ploop image blocks being modified.
2. Copy all blocks of a ploop image file to a destination system.
3. Ask write tracker which blocks were modified.
4. Copy only these blocks.
5. Repeat steps 3 and 4 until number of blocks is not decreasing.
6. Freeze the container processes and repeat steps 3 and 4 last time.
