[PATCH i-g-t 2/2] igt/runner: Add the rate limit feature for dmesg logs for runner

[Sobin Thomas <sobin.thomas@intel.com>]

Introduce --rate-limit N option to igt_runner to control the number
of duplicate identical dmesg records are kept in the results before
the remaining repeats are summarized. The default of 0 disables the
rate limiting.
This is introduced to limit the logs to prevent log truncation due to
size limit and test abort ocurring due to large dmesg logs.
