Some asv benchmarks fall off by timeout

[anmyachev]

System information

• OS Platform and Distribution (e.g., Linux Ubuntu 16.04):
• Modin version (modin.__version__): 477c5f6
• Python version:
• Code we can use to reproduce: cd asv_bench && asv run --show-stderr --launch-method=spawn -b TimeMultiColumnGroupby -b TimeMerge

Describe the problem

TimeMerge, TimeMultiColumnGroupby.time_groupby_agg_mean run longer than 60s(default asv timeout) or exceed memory limits.

For now, we can just reduce the size of the data. Further, optimization is needed.
