tests/migration: Introduce dirty-ring-size option into guestperf

Browse Source 
Dirty ring size configuration is not supported by guestperf tool.

Introduce dirty-ring-size (ranges in [1024, 65536]) option so
developers can play with dirty-ring and dirty-limit feature easier.

To set dirty ring size with 4096 during migration test:
$ ./tests/migration/guestperf.py --dirty-ring-size 4096 xxx
