chore: ignore mmds perf tests for m7g and m8g

Both m7g and m8g show volatility on mmds tests (and those tests run in
microseconds range). This makes A/B pipeline to fail all the time. Since
volatility is not high enough to be something to worry about just add
mmds tests to ignore list on these instances. Once volatility stops we
can remove them from ignore list.
