tests/migration: Introduce dirty-limit into guestperf

Browse source 
Currently, guestperf does not cover the dirty-limit
migration, support this feature.

Note that dirty-limit requires 'dirty-ring-size' set.

To enable dirty-limit, setting x-vcpu-dirty-limit-period
as 500ms and x-vcpu-dirty-limit as 10MB/s:
$ ./tests/migration/guestperf.py \
    --dirty-ring-size 4096 \
    --dirty-limit --x-vcpu-dirty-limit-period 500 \
    --vcpu-dirty-limit 10 --output output.json \

To run the entire standardized set of dirty-limit-enabled
comparisons, with unix migration:
$ ./tests/migration/guestperf-batch.py \
    --dirty-ring-size 4096 \
    --dst-host localhost --transport unix \
    --filter compr-dirty-limit* --output outputdir
